Power Door Locks Programmable Automatic Door Locks If your vehicle has power door locks, they are programmable. If your vehicle has an automatic transmission it will be programmed to have all the doors lock automatically when the shift lever is moved out of PARK (P). All the doors will unlock when the shift lever is moved back into PARK (P). On a vehicle with a manual transmission, all doors will lock when the vehicle speed is greater than 15 mph (24 km/h). The doors will unlock when the key is removed from the ignition. If your vehicle has power door locks, the switches are located on the driver's and the front passenger's armrests. Remove the ignition key and press LOCK to lock all the doors at once. To unlock the doors, press the raised area to the right of the key symbol. The following is a list of the available programming options and how to set them after entering the program mode: All doors lock/Only the driver's door unlocks: Press the lock side of the power door lock switch once and then the unlock side once. If your vehicle is not equipped with remote keyless entry, you may not be able to utilize this option.
