Peugeot Repair Questions? Ask a Mechanic for Answers ASAP
on some 405's there 's a key switch under the bonnet behind the l/h headligh to turn off the alarm so look for that 1st
1st thing to try is moving the switch and see if the ignition key becomes live all the time
if this doesn't work then If you have the code, on most models you can then enter the code (to go from 'red' to 'green') and then unplug the keypad then you do not have to worry about it again.
Caution: Disconnecting battery will need the keypad plugging back in and the code entering. This may also apply in its current 'state' too.Default code is 1111 , although the previous owner / seller should have the code, its not obtainable out of the ECU or from the dealer as its changeable very easily,
I'm not sure if the disable key switch is a switch on or a switch off
best to use a meter to do a continuity test into the wires with a scalpel blade and confirm what is currently connected to what as you'd imagine its not as simple as just cutting 1 wire
