Got to take it to the dealer. Most times they'll need to hook up a dealer computer to set the key to the alarm system .

contact mazda service department or customer relations department and request the code from them

1995 Mazda Theft deterent you dont have one. there is a keyless entry. a ant theft radio deterent. So you probable are having problem starting like turning over maybe the starter is non op or even a dead battery. So what does it do?

Its possible that you have some THEFT or PASSLOCK system that is armed when you disconnected your battery. Check in the owners manual the disarm procedure.

Hope this helps.

sounds like the anti-theft but im not sure how to reset on your model...hope it helps

When you take the battery cables loose from an anti-theft system, You would place a nine volt (9V) battery across the positive and negative cables to hold the memory chip in the systems. This allows you to remove the battery for a period of time longer than a few minutes. The system (anti-theft) is designed with a couple of capacitors in the system that hold the charge for a few minutes to allow changing of the battery. If the battery is removed for much longer than 30 minutes then the capacitors drain and the memory is lost in the chips.

You are going to have to go to the BMW dealer and have them re-write your system, and it will cost you about a hundred bucks. They have the plug in device that will restore the system and it is not sold to the general public. That is why it is called ant-theft, so if someone steals your radio it quits working.

Ignition lock is activated: You over rode it but still have original problem. Alarm system might be confused. SO....

1 disconnect battery negative (-) cable(make you have radio code if any) to reactivate radio, which works anyway if code was never set.

2 press brake peddle for 5 seconds

3 reconnect negative cable to battery.

use key and twist diver door lock to OPEN (this resets alarm which might have caused ignition lock module to activate.

You should be able to turn on the ignition, start the engine and shift out of park. Hope this helps.
