Ignition Barrel

[JEFFleCHEF]

Hi, I have a (sometimes) problem, I have to wiggle key to start car, sometimes ok, sometimes have to try a few times, any ideas??
Also comes up as theft protection system needs checking, think they might be linked.
Thank you for looking.

If its "key not accepted" then you have issues with immobiliser/chip/transponder ring.

I suspect you are probably getting "service theft alarm" messages which is due to a fault on the battery back up siren module circuit,and hence not linked to your ignition issue.
If so I wouldnt worry about ...loads of fixes around but most of the time they are only temporary.
I have two 9-5's and have spent far too much time and effort trying to fix the modules...in the end I just disabled the warning message to stop it nagging.

The ignition mechanisim is composed of three parts......transponder ring/key barrel/ignition switch.
Your problem could be a sticking barrel or a failing ignition switch(fairly common)

There is a guide on here for disassembly and cleaning which is worth doing in the first instance.
