Question about Radio Communications
1998 R reg Mazda MX5 1.8S with Cobra 5802 remote control alarm and immobiliser system factory fitted. I have the remote fob but not the key for the barrel attached to the siren unit. How easy or difficult is it to replace and at what cost? Is it cheaper to get a locksmith? Cheers, Steve.

You need to open the unit up ( remove the case/cover). Then remove the 4 screws holding the face plate on. Remove all the knobs ( they slip off) . remove any screws holding the meter on ( there may be none depending on which model you have ) . slide the meter out of the face plate and replace the meter with a new meter. Note: The meter light needs to be reistalled in the new meter. It simply slides out the side of the old meter and slide back in the new meter. Replace all the screws, and the jobs completed.
Good Luck and a good weekend to you.

YOU CAN ORDER THAT PART FROM COBRA ELECTRONICS ON THE INTERNET YOU HAVE TO REMOVE THE FACEPLATE AND UN HOOK THE DRIVET INSIDE THE RADIO IT LOOKS LIKE A SMALL RIBBON CABLE THAT GOES TO THE FACEPLATE. SOME TIMES THE DRIVER ITSELF IS THE PROBLEM. MANY SHOPS JUST DO NOT WANT TO FIX THEM BUT I DO.

The protection diodes are D23 and D8. they need to be replaces with N14003 or bigger. they are near the back right of the radio near where the power comes in by the transformer.
changing the channel selector screen is just unsolder the old one, and solder in the new one. Getting to where to solder it is a pain. You have to take a lot apart.
