#4: Re: keyfob/ecu! Author: macca1411, Location: Westhoughton, LancashirePosted: Thu Apr 28, 2011 9:25 am ---- Dropping it can do it, Ford used to do it if you left it without power for more than 2 minutes. www.206info.co.uk/Foru...c+key.html Thers the how to. Try that and see if it works. If not at least it's one thing discounted.

Wouldn't think so. Could be other things causing the problem.
Have you tried re-syncing?
Is the battery definately good (even if new, measure it.)?
#9: Re: keyfob/ecu! Author: oldbanger2, Location: m1/m18Posted: Tue May 03, 2011 4:28 am ---- tried re-syncing that works, but then after its locked for a few min and i try to unlock with button keyfob it wont unlock. i have to do it manually! i open the door & alarm starts going.. i put key in ignition & turn it ,alarm turns off.. key then locks/deadlocks/ opens the car..leave it 20 min.. keyfob buttons wont unlock car...battery is new....

Might be a dud.
Was it doing it before change of battery? If so its not that.
Clutching at straws but is your keyfob OK? Try with a mate's keyfob if available (sync it).

Need Peugeot Planet to code a keyfob to a different car
You cant sync a keyfob unless it has already been coded to the car in question BSI unit.
#12: Re: keyfob/ecu! Author: oldbanger2, Location: m1/m18Posted: Tue May 03, 2011 11:49 am ---- it has been working fine ,just started playing up 2month ago, thought it was battery , new one fitted still playing up..

Ah yes. That would make sense otherwise zero security.
Scratch that.
