Key fob stopped working!!

[JohnnyBoy81]

Today (Saturday 2nd may) my key fob unlocked car as normal I drove to the shops parked up got out and "locked" car but nothing happened I tried several times no joy so I manually locked it. Got home and put fresh battery in still no joy. I've changed the 5amp fuse in central fuse box but still nothing?!?! Any idea guys??

you may find you have to reprogram the key for central locking to work again?
or the pcb may be fubard.

Thanks gregers for the reply. I've tried the reprogram method ie insert key turn to position 2 then back four times remove key press any button insert again turn to position 2 back to 0 and it should be done but no joy!! PCB?? Thanks for the help it's greatly appreciated

pcb=printed circuit board,could well of broken

Thanks gregers as you can tell I'm not too familiar with a few things. I've put new battery in an checked circuit board visually looks fine strange thing is spare key doesn't work either( haven't put fresh battery in spare though) and still no joy. Done the reprogramming technique but nothing!! Could it be something within the car maybe? I've put fresh fuses in too!!! Thanks for any replies to hopefully shed some light on this.

Don't you have to program all the keys in one go?

[JohnnyBoy81]

Chrispb not too sure matey I'll certainly give it a go in the morning. When you say "all in one go" I presume you mean do one key then immediately do the other?

[Chrispb]

Yes I believe that's the way.

Success!!! Went to the car this morning unlocked it via the door mechanism using spare key didn't sit in seat just put key in ignition an proceeded to do the re-programme technique and hey presto it worked!! Strange as didn't work the other day only difference is I unlocked car then sat in then done it. Which means either I've missed some sort of time window or you can't be sat in seat to do it?? Either way it's now sorted and a big thank you to all that replied to my post👍🏻👏🏻💯 I'll keep posting on any subjects that may be of use to anybody!! Cheers peeps😀
