I love how everything on RU-vid just looks so easy and perfect

@4DIYers 10 лет назад

@ jkjerome1 Excellent tip, thank you for sharing!

@dianawilliams7856 8 лет назад

actually helped me with an after market ford f150 key fob ... looks exactly the same in build thx

@4DIYers 11 лет назад

You can swap the parts directly over with no problems at all... The worst case scenario would be you having to reprogram the fob, which can be done yourself. Just make sure that one of your door key locks do work and aren't seized. But this only applies if your vehicle forgets the coat for that key fob. You most likely won't have any issues though.

@quinettajohnson 9 лет назад

Thank you so much for this video tutorial. I purchased a used Passat and the key never worked. I was gonna take it to the dealer, but only God knows how much they would have charged me to do something so simple. 5 minutes of my time and $1, and I'm good to go. Once again, thank you. :-)

@BartSchram 4 года назад

Very clear and well explained! I had completely no idea how to open it. Thanks for your step-by-step advice!

@affiliatestud 7 лет назад

you must have had 100 or so VW dealer's swing by and vote "thumbs down" on this :) thanks for the video - very helpful

@4DIYers 7 лет назад

Lol, I wouldn't be surprised. I've had a small engine repair shop give me a hard time on Instagram for my small engine repair videos. Glad to help out :)

@4DIYers 11 лет назад

Yes the hatch lock should work. That key with the little wrench sounds like the valet key. So it only works in the doors and ignition but not in the glove box and I believe hatch. As for the sunroof drains, here's a thread I found explaining the locations forums.vwvortex.c o m /showthread.php?3191023-Sunroof-drain-cleaning-with-pictures (remove spaces). No problem, glad to help out :)

@4DIYers 11 лет назад

Your key needs to be reprogrammed into the car. It is possible that the key you disassemble wasn't the car's original key, therefore it has a different code. Once you replace the battery, it resets the fob therefore you have to reprogram the key. Follow the directions on here to reprogram your fob w w w .myturbodiesel.c o m/1000q/a4/vw-smart-key-remote-replacement. h t m (removed spaces)

@4DIYers 11 лет назад

In order to program your new key fob you will need another key which works in the car. I think you should be able to use your valet key if you have one. Just go to this link here which has step by step instructions w w w .myturbodiesel.c o m/1000q/a4/vw-smart-key-remote-replacement. h t m (removed spaces) About half way down the page.

@4DIYers 11 лет назад

Here is a tutorial for the upgrade forums.vwvortex.c o m /showthread.p h p?2941881 (remove spaces) You can actually reprogram the key yourself as long as you have a working door lock. But if you have to get a key cut, that can be costly.

@4DIYers 11 лет назад

If you have another key programmed to the car, you can reprogram it yourself. Here are the instructions w w w .myturbodiesel.c o m/1000q/a4/vw-smart-key-remote-replacement. h t m (removed spaces)

@4DIYers 12 лет назад

Unfortunately I haven't worked with the previous model key fob... Your best bet would be to go on a VW forum such as VWVortex and make a thread there and see if anyone responds.

@iwbowden 10 лет назад

God bless you for doing this - saved me a lot of time and frustration!

@4DIYers 11 лет назад

It may or may not work depending on the year of your MKIV. If the car doesn't recognize the key, it will start and then shut down right away.

@4DIYers 12 лет назад

Just cut away the little plastic rivet pieces in the corners with a knife or very small drill bit... Then glue in the board in the new case.

@4DIYers 12 лет назад

You have to swap the demobilize chip from the old fob to the new fob. The only way to disable it as far as I know is through VAGCOM.

@K.Kelly87 7 лет назад

Once again... Years later... Thank you.

@4DIYers 7 лет назад

Glad to help out :)

@4DIYers 11 лет назад

It's just a sliding fit in the case. You should be able to slide in a small flat screw driver along side it and pop it out.

@latoyanewsome9400 Год назад

Why has everything gotten so complicated! Move the emblem, etc. etc. etc. It used to be so simple. Those days are gone. But thank you sir

@4DIYers 11 лет назад

I'll always be adding new car videos... Some generic which applies to most car manufacturers, others model specific. Thank you :)

@4DIYers 11 лет назад

Thank you :) Nope, if you're only replacing the battery, you only need the first part. The second part is if your removing the immobilizer or key.

@FnlPrblm 8 лет назад

thank you for being thorough all the way through the entire process.

@4DIYers 8 лет назад

+FnlPrblm Thank you for your compliment.

@4DIYers 11 лет назад

If it opens up the same way, then I would assume it's the same, but I'm not 100% sure though. I know there is a few different variations of this fob that look identical, but they are held together differently.

@altimmons 3 года назад

Yea. Mine looks very similar but that central seam doesn’t follow al the way around. It’s definitely only half way (the back non button side)

@4DIYers 12 лет назад

@tigre909 Sorry for the late reply... You might be able to pull it apart and dry the components out in the inside. Some of the electronic might have also shorted out in the inside, so it'll be too hard to repair. I would think you should be able to purchase one of those ebay fobs, swap your key over, and reprogram it according to your car. Although I'm not 100% sure if this would work with reprogramming the new fob though.

@4DIYers 12 лет назад

@brightbr I believe you can buy just the buttons on Ebay. You would have to remove the circuit board itself by cutting away the little plastic nubs in the corner holes on the circuit it. After you would have to glue the circuit board back in.

@4DIYers 11 лет назад

The key fob? Should be able to purchase one off Ebay.

@4DIYers 12 лет назад

@laronwilliams16 You would have the cut out the small plastic pieces which work like rivets at the corners of the circuit board. Then you would probably have to glue it into the new fob case.

@4DIYers 11 лет назад

I actually sold the car about a year ago. Unfortunately I will no longer have videos on a VW MKIV unless I buy another one or work on a friend's car.

Thanks, I appreciate the video. I have a question though: what is the purpose of what you are doing in the second half of the video?

@4DIYers 9 лет назад

Z Gates No problem! The rest of the video is for case replacement, button replacement, or cleaning.

@blackrocket2000 6 лет назад

It helps if you are fitting into key, battery and pcb into a new plastic case

@brunosb0015 4 года назад

I was gonna say the same; only the first part for replacing the battery is what I needed

@4DIYers 11 лет назад

As for your seized door lock... Sometimes you can get a good quality penetrating oil which will unseize the lock. But if it's too bad, it'll need to be replaced. Friend of mine ordered a new lock assembly for his and I believe it was about $100 from the dealer. Now for reprogramming your key fob, you will need a working lock. You can use the lock on your hatch or if they're both seized, you can in behind the lock and push the micro switch manually.

@anitag8802 6 лет назад

Thank you for the video. I just put the key fob through the laundry. Duh! Didn't dig deep enough into the coat pockets. A little moisture in the battery compartment. Dried it out with Q-Tip and snapped it all back together. Still works.

@4DIYers 6 лет назад

Thank you for the feedback and tips!

@4DIYers 11 лет назад

The key fob itself might need to be reset. In section 3-1, page 29 of my owner's manual there is a paragraph about resetting the key. To reset the code, Press button A or button C one time for one second. The vehicle remains locked. The control unit recognizes only one key code via the master key. Lock or unlock the vehicle with the master key. The resetting procedure is now complete. A is the bottom button to unlock and C is the top to lock.

@Ratkill9000 5 лет назад

Thanks dude. This helped me swap out my battery.

@4DIYers 5 лет назад

No problem!

@4DIYers 12 лет назад

@dntcd The spring should clip in the button mark of the key. There is a tab which sticks past the outside diameter of the spring(shown at the pics in the end of the video), that part goes into the plastic casing.

@bartofilms Год назад

For those who bought Chinese knock off keyfob housings, only the quarter section below the VW emblem needs to be pried loose to access the battery compartment. Boca Lupo.

@4DIYers Год назад

Great tip, thank you for sharing!

@laca8612 Год назад

Thank you very much for the clear explanation. I did it at first time and you helped me a lot! It was clear how to separete the up and bottom part, but then I stopped and did not find any mark to split the half into two pieces (2nd separation). Then I found this video. At the side I used a mini crowbar (wider than a screwdriver appr. 10,5 mm wide) and it worked. Thumbs up! :)

Awesome to hear and thank you for the feedback!

@lennertkrueger1889 8 лет назад

For some time now the car was only locking with the fob but I had to manually unlock, so I decided to replace the battery and now the unlock button works! Thanks!

@4DIYers 8 лет назад

Excellent to hear and thank you for the feedback!

@MikeinCC 3 года назад

Good vid! VW wants the owner to bring the fob into the dealership for a battery swap, which is a joke.

@4DIYers 3 года назад

Thank you!

@4DIYers 12 лет назад

@scottgitech Thank you for the comment! It's just a small chip that slides into a slot in the plastic casing. I believe you can just pop it out and transfer it to the new casing.

@dedgerton 10 лет назад

The info you gave was good, but I feel like I've just seen the first act of a play. I was hopeful you'd also show me how to re-assemble. I'm not very mechanically inclined, so I find RU-vid videos helpful for step by step walk throughs.

@4DIYers 11 лет назад

Glad to help out :) As for the immobilizer, it should just pop out. It just sits inside that little slot, so you might need a small screwdriver to give it a nudge to come lose.

@lorenzoparedes2306 3 года назад

At $158 per hour of "labor", I would want that job. It's like they're obstetricians. Labor. Right. The last time I took my older VW to the dealership, there was a woman in the customer waiting area. The Service Advisor called her to tell her she needed to have a light bulb replaced on her car. The anticipated charge: $65.00.

@lorenzoparedes2306 3 года назад

Thank you for the video. I was having trouble with my remote fob, and I needed to read the FCC ID reference numbers, which is why I tuned to your video. Then, while I had the first part open, I decided to put in a fresh battery CR2032, which turned out to be missing from my battery "inventory". I'm one of those who doesn't like to wait until a battery operated device conks out before buying a battery for it. Anyway, while I looked, my VW fob sat without the battery inserted. When I reassembled the fob and tried it, it had corrected itself. Prior to that, it would not unlock the car. It would just lock it. Computerized gadgets are wonderful, but they can go bat$#÷+ for no apparent reason. At times like that, walking up to your car to put the key in the doorlock doesn't seem like such an inconvenience.

@AndrewDrane 10 лет назад

Just successfully changed my battery after watching. Thanks!

@j11mbr 10 месяцев назад

Thank you! My 2009 Scirocco 2.0 TDI would not unlock. Thought I would change the battery in key fob. Followed another video for '2009 onwards Scirocco' only to find the key fob was different. My key fob matches the fob in this video. Knowing I had the same key gave me the confidence to apply more pressure to open up. All sorted in a couple of minutes and tested out OK. I have had my Scirocco for 14 years and 136,000 miles now and have not had to change the battery before. Think I should complain to VW 🤣.

I had a 2013 and well, she went back to VW cause she was a TDI. Luckily I found a 2005 VW Jetta TDI. Unfortunately the key fobs are COMPLETELY different. I guess the battery completely died after 242k miles Thank you for this video. :)

@borinpich7420 4 года назад

Can the upgrade be done with the older style Bentley key (2004-2005) internal to be install on the newer style Bentley key (2006+) without the reprogramming?

@still34u 8 лет назад

I can't get the damn thing apart .. I pry with screwdriver, I pry with knife, I pry with fingernail.. I tried wobling it around, the thing is solid.. there's no taking this apart I guess.. and I am pretty sad, because my remote's battery is nearly dead, after 180k miles it works for like 5-10 feet on a "sunny day"

@Val-xm4iz 6 лет назад

U did good Bud, since We don`t have to pay the TAX Public opinion yet :) dont worry about thumbs down from the dealership people, I hope soon they gonna catch the engineers who have been pay to produce parts that falls soon after the warranty expires and end up like they do with the thiefs in China sunday morning on the stadium, cause if You pay premium for a high klas car You take a good care and the car fails This is simply a SCAM. Thanks again You helped Me a lot. Take care. Val.

@jkjerome1 10 лет назад

Hint for anyone who might have arrived here with an "immobil activated" message on their dashboard: If your mechanic tries to tell you the battery in the key fob has run low, he's wrong - the battery in the fob has nothing to do with the immobiliser - it only serves to transmit a signal to lock/unlock the car. The immobiliser reads an RFID chip inside the key that doesn't need a battery. So it would read it just the same with no battery in the key. I found a surprising amount of people suggest the key fob battery for this fault.

Every car remote is so damn difficult to service. It should be no difficult than changing the battery on your TV remote control.

@s.s.4170 6 лет назад

My key fob suddenly does not open the doors. It opens the trunk and the alarm but not the doors. Is it the battery getting weak or is my key fob dying? Never mind... I just figured it out. I put the key in the door and held it in the lock position. Then I unlocked the door with the key in the door. Voila! It now unlocks the doors.
