My Y-reg (no spring chicken!) 306 remote car key casings had become worn out, to the point that the 'open'/'close' buttons no longer worked due to 'plastic fatigue'.
So I bought a new casing from a fellow on eBay and received it yesterday. Apart from the absence of the Peugeot lion on the back, the casing was identical to the old ones, only new and with functioning buttons.
I 'transplanted' the cut key (metal), as well as the little electronic bit+3027 battery, without any problems. Checking, the remote control worked perfectly for both opening and shutting, as expected. I thought no more about it.
Then, this morning, she opened again normally with the 'new' key but the car wouldn't start for love nor money. She cranks over enthusiastically but doesn't catch, which makes me think the problem is fuel supply - immobiliser?
Reverting back to the old key, now empty of all electronics, she started without problems! I've since switched back and forth between both keys several times and it's clear: one (new) serves as remote but can't ignite the engine, the other (old) does not work remotely but has no problem igniting the engine!
Does anyone have the slightest idea what might be going on here?
