Central locking i have a mazda 626 2ltr s-reg lxi 98. My key fob remote locking has broken, electrical experts have said that it is completley broken. to get a replacement was going to be a dealer part and was going into the £200 mark with programing it. So i bought a Portman Car alarm from maplins that i would fit to the locking mechanism. This alarm is designed to take on the remote locking and unlocking of the car but i need to know what type of locking i have e.g 'revers polarity' ect. also my haynes manuel is rathre vague as to where i can locate the control box for my central locking. Any assistance or random thoughts would be incredible- i'm in the hands of you experts. If it helps, in the door panels thier is a soliniod that conects to the back of the locking barrels. this soliniod both triggers the central locking and the car alarm and the dead locks.

Removing the door skins are not hard, the problem is that they normally use a special tool. Without the tool you may break a few of the plastic clips. If so no worries go to your local automotive department and look for the clips. 
You will also have at least one screw that attaches the skin to the door frame. Usually remove the bottom of door panel and work around both sides until you get to the window. Then remove the screw and unplug any of the power options..
Haynes or  Chiltion manual for your car should show you details.. It is easy for the average DIY person.
The handle is just as easy. Do you have metric and torx because you will need them.

Try this, it works on several 2002 models:


Step 1: Open drivers door and leave open.

Step 2: Lock and unlock the drivers door using the power door lock switch on the door.

Step 3: Insert key into the ignition.

Step 4: Turn key to on position and return to off position. (IMPORTANT - use ON position NOT ACC position). Do this 3 times within 10 seconds. Leave key in the ignition.

Step 5: Open and close the drivers door 3 times. (Door should be left open after this step).

Step 6: ECU should respond by locking and unlocking the doors.

Step 7: Press any button on remote #1. ECU responds by locking and unlocking the car doors.

Step 8: Press any button on remote #2 (etc.) Each time the ECU will respond by locking & unlocking the doors.

Step 9: Remove the key from the ignition and the ECU will respond a final time with a series of door locks and unlocks. You're done

I had a similar problem with a second-hand Mazda2, was intermittent too so the seller kept telling me it was OK. Eventually turned out to be a loose connection with the fob, I bought another off eBay and billed the garage for it, found instructions for programming it online and it's worked ever since.
