The battery condition is critical to the operation of the car as many functions - ignition, steering, sliding doors, air conditioning all rely on the battery being up to scratch. Even if the battery is OK then it is possible to get yourself LOCKED OUT of the car.
Please help!! The key fob will not operate the door either electronically or manually. I have also tried the spare. When I put key into door handle and turn I can not even hear an unlock click. I locked out of the car....any ideas?
This is a very bad situation to be in. The only obvious answer is to break a window (some say the driver's door window; some say the small window by the rear seats) so you can get the ignition key in the lock and start the car. This seems to clear the problem however see below for a less damaging solution.
This can happen:
if the battery goes flat (eg after long standing, lights left on, battery failure).
if you disconnect the battery after closing all the doors and windows and then close the bonnet.
if there is a door problem and the doors won't open on the remote or with the outside door handle.
If it appears everything works except the doors then suspect the in-door actuator which can either operate too slowly, not at all, or be jammed in the open position.
Inside the car, sitting on the drivers seat, pull the inner door handle and listen - Yves has posted a very good demo of what a worn actuator sounds like and what a new one sounds like
If this actuator is faulty, it can shut down the Door ECU - and it stays shut down - so the doors won't work. Clear via the reset procedure (but if the actuator is faulty, it will immediately put the ECU back into shut-down mode)
If you keep trying the doors, I suspect it can also shut down the security module in the BSI - but I don't know for certain. Just imagine yourself as a burglar and you can see the car is protecting itself.
Do not open the bonnet, lock the doors and take the battery out because if you (or some helpful assistant) then closes the bonnet there is no way of opening the doors or tailgate.
The only way out of this situation will involve grovelling under the car as follows: do wear glasses in case there is a spark or oil drops into your eyes.
