2 button key fob not working
« on: 17 January 2019, 16:43:31 »
Yesterday out of the blue wife's key wouldn't open the doors. The little red led on the key is not lighting up. It's a later two button fob where the shell separates from the key. Car is a 2003 CDX estate, 2.2 16V.

I changed the battery but still doesn't work. If I press on the top of the battery then the buttons work. The battery holder seems not to be securely attached to the circuit board underneath. Pressure restores contact.

So removed the circuit board and it seems that the earth side of the battery holder has fractured where it is soldered to the circuit board. Two small for me to solder. Especially as it's on the bottom of the battery holder.

So I guess I need a new shell with circuit board? What do I need to buy and what's involved in programming it to the car. I still have the transponder chip in the key section.

Thanks,

I managed to repair one by soldering fine wires across the fracture.

PM me your address, and I'll send you one that I bought new about 4 years ago.
Key(which be any use to you), remote and immobiliser chip.


You will have to get the car programmed to it, but that's true of any replacement

Remove batt holder completely.

Extend the broken leg of the battery holder using stiff wire - a bit off a resistor is ideal - and then solder it back in.
