Immobilisor minor issue

I have a slight issue with my immobilisor/alarm key fobs. They will lock and unlock however they are a bit iffy. Sometimes they work first time no problem other times (like today) it takes an hour of pushing the button!

So I think it's the receiver. Please correct me if I'm wrong though as it happens when using both keyfobs.

If I change out the receiver from a scrapped car or something will everything still work? Or will I need a lot more than just the module and maybe a keyfob that matches it.

Please help!

Keyfob battery, couple of quid from asda. This happened to me with both fob batteries going within a couple of days, if you've never changed the batteries before they'll be the same age. Fob just pulls apart to exposes the battery.

Thanks for the input but I should have said, I've changed both batteries.....

I thought it was the sender in one unit but because both were playing up I guessed it was the receiver.

The receiver is located above the speedo in the instrument pod. I believe they are matched to the ECU so changing may not be simple. I would have a look and check if the receiver multiplug is loose or dirty.D..

Just what I was afraid of! Didn't think it would be easy..... it never is!

As I say, not sure if it is the receiver but it seemed logical as both remotes are not working....

I'll have a dig and see if it's something simple. Fingers crossed.

Thanks for that Dann.

Well I took the dash cowel off and had a look. Everything was tight. I took off the connector gave it a wiggle and a bit of a clean then put it back in.

No idea if it's fixed but the remote was working ok. Maybe not everytime but most times which is an improvement.

I took pics of the receiver too if I need them.....

Not quite the same problem but could be a problem with the aerial

Thanks for that. Mine is on the top but the aerial cable is shorter than I thought it would be.

Seems to be better now. Just don't want to be stranded!
