Have a Car Question? Ask a Mechanic Online.
Hi, I am a professional certified mechanic, with an engineering background, and 35+ years experience. I will do my best to assist you. Also keep in mind I don't know if you are a pro or a novice, so feel free to add any additional info at any time.
What you need to do is to contact a Mazda dealer with your VIN number for a radio code. When the battery goes dead, or gets too low the electronics in the radio assume the radio has been disconnected/removed/stolen. Basically the radio always has power to it, so it should normally see a no or low power situation. It has an anti-theft system that shuts the radio down in a low power situation, assuming it has been stolen/disconnected. You need to get the code and enter it. Most Mazda radios only allow 3 attempts to enter the code then they require a secondary code. It's a pain, but it is what it is, and it is what you have to deal with to get it going. Also there is no trick, or bypass all straight up pain in be backside, LOL. Get with Mazda, get the code, and you can get through this. Good luck with it, have a great day, and Thanks for using Just Answer.

I am not so concerned about the radio, but more the engine. I can't start the car because it will not crank. I do not know if there is power to the starter. there is power to the dash instruments.
do I need to ask again? I received notice that you required more information, do you still require any more info on my problem?
I am OK waiting, how long do you think it will be?
Wayne, the key does not work to turn the alarm off, the key will not open the trunk or lock/unlock the doors. I do get dash lights, the odom shows the milage, the lights work, the horn works, the turn signals work. the red light on the top of the steering column flashes. The car is manuel geared. I had to take the fuze out for the horn, it annoyed me and the neighbors.
Wayne, did that and the battery checked out fine. I will have to look again but I remember it being 100% 14 amps. Also I tried it with our second car jumping the battery, no effect. It seems as there is no current getting to the starter. when I try and start it, the security system will flash for several minutes after I try to start.
appreciate not chasing my tail. I don't but I will get a multimeter. whats next? second key does not work either.
Let me know when you got your multimeter and we will start checking circuits.
You know I just thought about it but you dont happen to have another mazda key on the keyring or in your pocket do you? Just to be sure.
no second key, thought about that as well. I only take one out at a time. Holidays here in Germany, will take another day to get a multimeter. To follow up, the battery is charged at 100% the amps are 14% I have tried to jump it and still no power to the starter. the security light flashes after every attempt to start, I am wondering if there is a way to bypass the imobilizer or is that a bridge too far?
OK I have a multimeter and am ready to get started. I also tried an On Board Diagnostic tool to see if it could show me anything, there is no power getting to it. the machine would not power up. I checked it on another car and it functions fine.
I have discovered the imobilizer switch next to the fuze box, it gets the car started. I still have no radio and the remotes do not operate the door and trunk locks. I think I have the code for the keys and the radio, my next step is to get that going. I realize I may need a dealer to cut new keys and re-program the system.
I think I am good with it now. I'll let you know if the dealer can't help.
