Keypad malfunction

Unread post by Ltpump »

Hey guys, I have an issue with my car – a 2011 Citroën C4.
I disconnected the keypad because it stopped working, and since then the car won’t start.
I still have the keypad with me, and the car’s ignition circuit is disconnected.
If anyone can help, I’d really appreciate it!”

Welcome along

That is not an OE item - presume someone has added an aftermarket immobiliser. Unfortunately unwinding that might be a real pain. Is there a maker's name on the pad? Maybe you could get a new one to avoid having to unwind all the previous work.

it would be a case of following back all the wiring & finding the circuit cuts and re instating them.
Looks like a bit of a mess in there.
Finding the make & model of the system would probably help a lot.
