All Ford vehicles have a central locking system that were manufactured after 1993. The Ford focus has always had the central locking system.
Try changing the fuse
Central locking is the security system on many vehicles, which makes it very important in many lives. Central locking allows for sound of mind when a vehicle is out of sight and in a potential insecure location.

What is a diagnostic port
By using central locking system of cars, passenger can lock or unlock all the doors of car pressing a button or flipping a switch.
Under the bonnet there is a fuse bow near the bulkhead. Fuse number 63 is central locking. Its a 20 amp fuse.
A Ford dealership will have the information about the cost of replacing the central locking system on a Ford Fiesta. Another way to estimate the cost is to get a quote from an auto part retailer.
First of all, there's no such thing as a 1989 450sl...they stopped making 450sl's in 1980...then they went to the 380sl for a few years, then finally the 560sl to finish up the 107 body style run. Secondly, if we are talking about a 1979 450sl, there is no central locking pump. The entire central locking system uses the engine's vacuum. There is a storage ballast underneath the front right fender....it reminds me of 9 black balls stuck together with a single vacuum line coming out of it. The doors, trunk and gas flap are all controlled by the central locking system. Each has and needs its own vacuum diaphragms...that are powered by the vacuum lines. If your central locking system isn't working, get a vacuum gun and test each diaphragm to see if they're working properly. There is also a small vacuum valve in the left door that might also need replacing...you should also check all the pertinent vacuum lines and rubber connections for leaks. One leak will screw up the entire system. Also, if you do have a 79 SL, you also have the worse climate control system ever made...this system also depends on a vacuum supply to function. That is a highly complex system that your mechanic should work on, not an amateur
If the car has an alarm system or remote locking (Key fob) the locking control box is behind the side trim in the (UK) passenger footwell, if there is no alarm there is no relay box the system works off the door being locked and it sends a lock command to the other door
That pump operates the pneumatic central door locking system.
Yes you can put an alarm on a car with no power locks, you can even buy central locking system that you can fit to a car with no power locking system that will connect up to the alarm system. Danny from Bee Mech Mobile Mechanics Find me at www.beemech.com.au
