Glad it helped!

@@Maknificent12now )p

ABSOLUTELY!

On most cars, yes But on some cars like 2007 mb e320 There is none This is the best way

Absolutely! Happy to Help!

where did you hook up the cables for your e class?

@@xaviers.2271 As far as I remember, (-) there as on the video, and (+) immediately to the red wire. It is very difficult to make mistakes. If it is quite difficult, you can check it with a voltmeter. But the idea is as on the video, and everything is in the same place.

I did like you showed and it worked for me, thank you

2003 S 430

@@Maknificent12now I have an 03 e320 that was sitting while I got enough time to scrap or sell it. Dead battery, and of course figured out the problem I was in after the first 20 minutes messing with the valet key and the key slot. No matter what I do, that bugger won't open. Will have to get the MacGyver pants on and see how I progress... Wish me luck!

Satan designed this stupid trunk lock and battery design to screw with us. These cars are money pits.

On my 2005 E500 W211 there's a two step process for opening the truck with the blade key. Insert blade key, turn to approximately the 10 o'clock position and then lift up on the lever above the licence plate while opening the trunk.

Yes, the valet key works on my 2002 S430 also. It always takes a lot of fiddling to get it to work however, I keep turning the key and pushing the button and it eventually pops the trunk. I will try the 10 o'clock position first next time, thanks Lockemeister.

glad for it!

Glad it helped!

@DapperDon trunk button 1st then tried key fob and worked just as well

@JuanFranciscoPurdon CRAZY situación! 😜 As long as battery charged keyless “should” work. ONLY issue you might face is SOMETIMES if Benz battery left dead too long it gets amnesia sometimes requiring reprogramming for basic features like keyless entry Not sure length of time so get her charger ASAP & let the community know how it worked out for you 🤙🏿

Maknificent12 thanks a lot for Your reply! My car Is a 04 VW Touareg but I’ve found This video helpful!

Niceeeeee! Glad it helped!

Hie would this work on my W140 S320?

Glad it helped bro!

@ugotsome PREACH!

ugotsume well what do you do cuz I need to know

Yupp use your manual key , if you dont have a manual key thats a whole different problem

1bucemup1 yes it would but the cables are different you gotta know which one to put it on

And 2007 E 280 petrol please replay

thank for the anwsers guys

How do you open the trunk?

How

Maknificent12 Where the license plate lights are.

thnx for feedback!

it help?

Maknificent12 yea

😂 If it were only that easy. Many people have experience that even with the manual key it either does not work or stars have to align for it to work. Hence the vid

Lol That’s completely Diff video Need a Locksmith for that one 😂

@@Maknificent12now lol it's cool. I got in without the locksmith

You’d have to Use jumper cables and connect to battery or another running car 🤷🏿‍♂️

Good stuff

I could be wrong but I’m not the only one that had trouble. I wish everything created works as it was supposed to.

I like this method better and have used it twice; once on my vehicle and again on a friends. Who the he'll has time to locate the alternator then hope you have comnected properly or even knows what it looks like....I just want to drive, not be a mechanic. Both are excellent suggestions this is greaseless and dirtless as I keep my car immaculate.

@GarvinHarrison hey bud! U know that’s a great ? bc that’s +- how I do it w/ all my other vehicles. I know there was a reason but honesty don’t remember. Perhaps I was thrown off by Benz battery being in trunk, I just like adventure🤣 , or maybe just complicating the simple 😂 I dunno 🤷🏿‍♂️ Regardless, i suppose here’s another way to get her done 🤘🏿

garvin harrison can i have your # bro my battery is dead n I’m trying to open my trunk

@@selfpaiddon3709 hey bro you get help you needed/question answered?

@@selfpaiddon3709 If you were serious I would help, but I'm thinking your not.

garvin harrison i had got it open i was using the wrong key but Preciate it

Except you’re driving a KIA…. Not everything is about money…

Dude all makes & models are expensive 🤦🏼‍♂️🤣🤣 i own a e55 & brought new airmatic suspension for 300 each & its been 1year with no problems you just gotta look around for parts instead of going through mechanic they will charge you shyt loads 🤦🏼‍♂️🤣🤣

Nah you bought a bad one just say that

True

When you don't know something, it's just better to be quiet, alot of Mercedes car when the battery is disconnected, the latch on the trunk will not work and no key will open it, and this info, I got if from a MERCEDES dealership when I went through the same issue, so yes this is how at the MERCEDES dealership they will open your trunk....

@@davidmendes563 Call Mercedes and they will confirm that when you use the key and the release latch, it is purely a mechanical operation. They will further confirm that they have never manufactured a car where the trunk/boot cannot be opened in this way. When you have a situation where it won't release, it's due the release latch not functioning properly.

🤣 not all keys were created equal my friend. Tried the key. Up to point of breaking it. Over time sometimes the mechanism just gets corroded stuck hard to do or just plain impossible. The video was meant for those who like myself despite multiple and varied attempts key wouldn’t do it. Cheers

I would have said the say thing. You would think that it is just a mechanical key. I have an issue with my car, S500 2003 where the battery can only be started if it was used within the past 12 hours. It has a short somewhere that is draining the battery. I have had multiple mechanics try to fix it without success. I have used the metal key to open the truck more times in the past three years that I care to count. I know how to use this key. However, I let the car sit to long with a dead battery. For the first time, the metal key would not work. It just kept turning. I tried everything. Believe me I know how to use the metal key. I connected a power source as described in this video. Nothing after ten minutes. I decided to try the metal key in the truck. It opened right up. The little bit of power connect under the dash did something. I am not charging the battery directly in the trunk now. I thought I was going to have to replace the key cylinder. Note: my power source clamps / connectors would not attach to the nut under the dash because they were to big clip on. I put my socket, #13, on the nut to make the connection with the red / positive connector. It was enough to get my key to work. Please don't be so quick to comment. I think the guy who made the video would have used the key if he could have. My alternative was to have a hole drilled behind the license plate and pull the lock cord to get the truck open. The first choice is always the key. I personally do not understand why even a little power is necessary to use the metal key. But it is true.

@@ricku2411 my friend.. i really don't know what you're saying.. I've opened the trunk of my 2000 S class with the metal key many times without even having a battery connected.. because my car was sitting for a long time i always took the battery out. Like this: 1- lock the car with trunk open 2- take out the battery. And that was it. Next: after more than one month; 1-open the trunk with the metal key 2- connect the same battery that was left there.. and wait about 1 minute.. then unlock and start te car.

I know, it doesn’t make sense. I’ve done the same as you. I would disconnect the black cable if parked at the airport and use the metal key to get in, then connect the black cable and be in my way. I have had to use the metal key at least 100 times. Never failed. This time the key kept going round and round. I thought it was going to break. I even needed a wrench to turn the key. The mechanic told me they do fail after a while. They have replaced many. I thought it had failed and needed to be replaced. After I connected a little juice under the passenger side dash, I decided to try the key again. To my surprise it opened like it had so many times before. Before I dismantled under the dash, I tried the key just in case. It failed! so, I went under the dash to connect some juice. Logic says, it doesn’t make sense. Both of us have disconnected the battery and used the metal key before. ???? I’m glad it did work. Maybe someone can tell us why. If your key ever does fail and you have no power, give it a try. What do you have to lose?

Wow your a smart truck aint u
