Key Battery Vauxhall Opel Corsa Combo 

You're very welcome, glad it helped :)

Hi, did you get this sorted? I've been away

@@TheCarKeyMan Not yet budd 😞

Ok, so when you press each button on the key, do they both feel the same?

@@TheCarKeyMan Yep! They feel the same

Hi, we’ll it depends if it’s transmitting or not. You need to find that out. Did it work before you changed the key battery?

Thanks for watching :)

You're welcome :)

Hi, ok so if one of your buttons is working then the coded to the car. There are normally two reasons for the lock button not to work. The first is that the little electronic switch underneath the rubber button has fallen off the circuit board and needs soldering back on, or a new one fitted. Please don't use superglue as it will ruin the key and won't work. The second is that the car door is sightly open so the car won't let it lock

You're welcome Nikolas :)

It's a CR2032
