Key Fob Help Please

[Jemanw]

Hi, I've recently bought a Berlingo 2003 forte. The key fob was damaged so I bought a new case for it and replaced the battery. When I use it the lights on the car flash like it would and it sounds like it locks however it doesn't lock anything and only unlocks the back sliding doors. Any advice would be appreciated, thanks

I am having similar troubles and I think it's not the fob, it's possibly the BSI computer in the car.

- Does it start the car? If so, the transponder is probably OK. Additionally, the lights flash so I think the fob is paired.

- Did it use to work before you swapped the case?

- Does the central locking work when you try the driver's side manually, in the key hole? Do all doors unlock when you do this?

- Do you have a key without a radio? If so, does that unlock all the doors when you try it?

Thanks for the reply.

Yes it starts the car.
No it didn't work before, that's why I thought it just needed a new battery, the buttons did nothing before battery change.
When using the key in the driver's side it will only unlock that door, no others.
And if you mean by without radio, just a plain key then yes we have one but no it will still only lock the door you put the key into

That's precisely the same issue I have. I took it to a specialist and he found some issues with the wiring in the driver side door, but nothing to explain why all doors aren't locking.

Took the BSI out and I think one of the relays inside it has gone, so my next step is getting that fixed.

This thread was very handy

Also, if you search around there are similar central locking woes out there.

Ah I see. Thank you for your help. We have a mechanic friend that we are going to see this week. I'll reply to this post as to what he says incase it's useful to you.

Did you get anywhere with this? Just wanted to say - repairing the relays on the BSI fixed my issue.

Ah cool, thanks for letting me know and we haven't been to see our friend yet but I'll tell him your solution and I'm sure it will save him some time. Thanks again.
