Ignition return spring

I have an M reg Peugeot 306 XLD.

Recently the ignition key return spring has given up.
That is to say when you turn the key to its furthest position to start the
engine it stays there and doesn't spring back. You have to manually turn
the key back. There is no spring action at all. Thinking it might be a
sticking spring I squirted some WD40 in to the ignition key slot but this
hasn't made any difference. Is this repairable or do I have to get a new
ignition key lock ?

Thanks

 

usually caused by swarf in the lock,you could try removing it and rinsing it
through with parafin,but to be fair its probably best to get a new one due
to the risk of it sticking and being unable to remove your key

 

Peugeot said I need a new lock and that I would need the key number if I
wanted to have just one key to operate the ignition and doors. What do
Peugeot key numbers look like ? If I remove the old lock would it be
marked on it somewhere ?

Thanks

 

Hello,

Theorically, on older Pugs (at least x05 series and early x06 series, I
think) it was a small metallic plate, which should not be lost. For example,
it stays on the spare key key ring (my case). Later Pugs use a card to give
to the service team, ISO size (i.e, smart card / banking card size). Report
to your manual to see what system it should be.
BTW, the VIN may be enough. It worked for my brother (although not as
"reliable" as keys nr).
