C900 Keyless Locks
Step 1 - Disassembly
Remove the door panel and remove the old sensor unit.
The door panel is removed by unscrewing everything that holds it on!
Take note how the door lock mechanism is connected to the actuator. Then disconnect the wiring and the rod and remove the sensor.
The old lock sensor looks identical to the new actuator.
The main difference is that it only sends a signal to the central locking relay pack, it can't receive any signals.
Swap over the bracket and bag onto the new actuator and bolt it up in the same manner as the old one.
Don't worry about the wires yet, we will get to that next!
Remove the knee bolster to get access to the central locking relay pack. It's located next to the heater core opposite side of the pedals.

Remove and unplug the relay pack by removing the top clip and the metal bracket holding it down.
Now it's time to wire it all up!
