Question about 2005 Peugeot 405
I have changed the batteries in my key for a peugeot expert 1.9d and now the remote locking wont work, how do i reset the key?
I have done this procedure for my peugeot 307, but you can give it a try for your Pug expert and let me know if it works.
Disconnect the battery for 5 minutes then after connecting the battery perform the following steps
1. Turn the Ignition switch to the ON position using your key.
2. Press the LOCK button for 10 seconds. It will set your ECU in programming mode.
3. Remove the key and wait for 10 seconds.
4. Press the buttons on the key repetedly for operation (lock und unlock doors) to synchronise the key signals.
5. Again turn the ignition on and start the engine.
6. Turn the ignition OFF
If fails in step 4, then disconnect the battery and reconnect it and wait about 10 minutes to check the remote. Some new ecu units synchronises itselfs if you disconnect the battery while in programiing mode.

check the obvious first beacuse this doesnt really seem llike a problem with the key , if the key needs resetting you will not be able to start the car with that key. has the battery in the key fob
been low or been replaced recently
, make sure all the doors are properly shut includind the bootlid , as most modern cars cenral locking systems does the lock unlock if a door is only partially shut,
resetting a key is not a diy job . the key needs to go to a locksmith or peugeot dealer .
let us know how you get on
and please rate
