New remote keyfob on the cheap
#1
After nearly ten years' service, my buttons wore out and fell off my old remote!
   

A certain online auction site has lots of cheap replacements, such as "CITROEN XSARA PICASSO NEW REPLACEMENT 2 BUTTON KEY FOB" for under a tenner - my pic shows what you get (if the attachment works - it doesn't show up in Preview?!)

(btw a 20p piece is a perfect fit in the groove to prise the keys open)

Unfortunately there's a small chip moulded into the original key - for the immobiliser - right next to the top of the key 'blade', and I had no idea how to get it out.

I was hoping to snap the circuit board into the new key's half with the new buttons, and join that to the old key's half with the battery and key blade. But the old and new don't snap together.

So I came up with a work-around. I transplanted the battery clips and circuit board to the new key, and had it copied a the local locksmiths (around a fiver).

My nice new key now gets me into my car (the radio remote works as well as it ever did - and if the battery fails the blade opens the doors manually) and is the one I carry everywhere. The old key is kept hidden inside the car, and is used for the ignition!

The new key won't start the car - the starter motor cranks, but an immobiliser warning light shows up on the dash and the engine doesn't fire into life. There are no other ill effects (no lockout leaving you stranded) - using the old key starts the car again, no problems.

I know proper replacement keys are expensive, so a solution that cost just over a tenner has left me relieved to have my remote locking again - being able to run inside when it's raining without hanging around messing about getting a key into the door the embarrassing old fashioned way! :lol:

Thanks, but how on earth do I dig out the RFID chip from the key shown in my pic?

Anyway, I'm getting used to the 2 key solution, and the locksmith didn't do a 100% perfect job on the copy, it only works one way around in the locks... sigh....

Insert a small screwdriver down the r/h side and it should just lever up.Confusedalut:

My chip was easy to get out with a watchmaker screwdriver and popped in my new key easy
