By the way...how does the smartlock work in these things? Is it something in the key or what? I notice that it seems to disable the smartlock when I turn the key.
When you turn the key the immobiliser is disabled and you can start the car. According to my Gregory's manual "The engine immobilisation function is carried out by the electronic ignition switch/lock cylinder assembly in conjuction with the control module.
When the key is removed from the lock cylinder, the system is armed and the warning lamp will flash briefly with a 1.1 second pause between flashes. When the system is armed, the remote keypad can operate the door locks.
If the control module recieves incorrect codes from the ignition switch/lock cylinder assembly, the system enters the immobilised mode which is indicated by rapid flashes of the warning lamp.
In the immobilised mode, the starter motor will not operate and the engine will not start.
If the cause of the immobilised mode was a discrepancy in the signal from the ignition switch/lock cylinder assembly to the control module, the engine should start if another attempt is made.
If the cause was an illegal attempt to start the engine, such as bypassing the ignition switch or applying power directly to the starter motor, the immobilised mode will continue and the engine cannot be started."
The owner thought the car had remote central locking, and that the module had been lost.
If you didn't get remotes with the car they can be purchased from your local ford dealer for about $75. The car then needs to be programmed to the remotes, but if you need that info just ask on here.
But I thought that Smartlock is just the immobiliser (Does having Smartlock imply remote central locking also?)?!
Smartlock is just the immobiliser, the ecu controls the remote central locking I believe.
