How to reset immobiliser - 2004 Peugeot 206 SW

try using a scanner to reset the immobiliser. It may work

what you are missing is that the key fob relates to the immobiliser that has a corrupt program from the dead battery. The keys will be ok so use a scanner to reset the immobiliser in the cpu program. Just reset the ecm and the immobiliser will reset

1998 golf is a mk3 and does not have an immobiliser. Your problem is elsewhere.

Immobilisers may intercept one of three circuits; typically the low-voltage ignition circuit and the fuel pump circuit. Some may also intercept the low-current starter motor circuit from the key switch to the relay. The Immobilisers can be set to intercept these circuits IF you use a key that has been copied or someone tried to start the car with the key for another car. Once activated, most of the time they are on a timer, meaning they will reset in 10 to 20 minutes. You can try and reset yours by disconnecting the battery, remove both cables and touch the two cables together for ten minutes. Now if you have a radio that needs codes to reset it be sure you have the codes before disconnecting the battery. Some Immobilisers use a magnetic switch to turn off the car. buy disconnecting the battery and touching the cables together you will kill the magnetic field and reset it. Hope this helps fixya up.

The mechanic that you talked to was exactly right
