Question about 1991 Peugeot 405
I have a M reg Peugeot405 Automatic saloon The key plipper is still functioning but car battery is flat. If I open car with key only I believe the alarm will go off ! How do I turn the alarm off while I charge the battery using booster cables connected to another car ? I don't want the alarm sounding for a prolonged period as the car is in a residential area and outside a school
Hi Alan Yes you are right the alarm will go off unless the battery is that flat that it doesn't have enough power to sound the alarm. This is the old catch 22 situation. Have a pair of grips and a 10mm spanner ready to minimise noise time. If you have the radio code, you can unlock it with the key, pop the bonnet, and disconnect the Negative lead with the green thumbscrew and pull it off the terminal first to reduce the risk of shorting, also tends not to spark as much as the other way, then when you come to disconnect the Red Positive, theres no way you can short your spanner to the vehicle earth. Ahhh, Silence! then remove the Positive lead and charge your battery, remove the cell plugs to let the hydrogen gas escape, and make sure its well ventilated, otherwise, BANG could happen, unless its a sealed battery, then don't worry. Once its charged reconnect in the opposite order, but be ready with your keyfob, or better still have a mate ready as soon as you hear the alarm, lock then unlock. Then just re-enter the radio code by pressing the respective number buttons. If you don't have the code, you will need it reading, usually about £10 - £20
