peugeot 306 - Peugeot 306 ignition lock change - richiek

Hi guys,

Have a pug 306 hdi and a couple of days ago the spring return in the ignition barrel went sloppy and won't return to it's correct position automatically so went to a scrappy today and got another barrel together with it's key. Trouble is after we fitted it the car will turn over properly but won't start. I presume this is something to do with the immobilizer transponder so put the old lock and key back in and sure enough the car started first time. Does anyone know if there is a way round this problem or if not is there a way to repair the original barrel so that the spring return works again.

Many thanks

The spring return action is in the ignition switch.So you could transfer the s/hand switch onto your original barrel.Another possibilty is some of these peugeot keys,the metal blade part of the key is removeable,so it is possible to fit the s/hand blade into your original fob.hth

Hi , you dont say what year it is,asume its a 1999 onwards, you are right its to do with the immobilizer, and the suggestion of changing the sping over is the best way. distmantling the switch and putting it in the original switch a bit fiddly, or also as previous suggestion fit the key blade into your original key fob. Alternatively go back to the scrap yard and get the ECU ,Alarm module and transmitter all from the same vehicle your key came from also the.

The alarm module has the immobilizer code in , the transmitter ring around the lock picks up the code from the key sends code signal to the alarm module if it matches module sends signal to ECU to allow fuel etc to start the vehicle.

Hope that helps.
