2009 Honda Civic Key Immobilizer (Page 1/3) Jake_Dragon FEB 04, 02:56 PM 2009 Honda Civic. Car sat too long and the battery died. I charged it up and when I tried to start the car it will start then die. Key Immobilizer is flashing so the ECU has lost its mind and thinks I am trying to steal the car. Looking for a scan tool that can reset the immobilizer and let it recognize the key. Anyone have a model number that works and isn't $700 This is my fault, I know it and I take full responsibility so don't judge. I just need the car to start so I can get it back on the road. ray b FEB 04, 03:51 PM fun key guy at the local swap meet wanted 80 for a key with chip he had a reader / burner that did the keys is that what you need ? or some other device for the car end and not the key local locksmith ? or indie honda shop ? rob a bank then go to the stealer or just rob the stealer for the needed device ? ray b FEB 04, 03:54 PM local auto parts maybe ? try one that sells keys for the chipped cars williegoat FEB 04, 03:56 PM If you are still in Long Beach, park it on the street with the windows down, wait a few minutes for a thief to come along and start it, then shoot him. Jake_Dragon FEB 04, 04:14 PM While I like the idea of putting it on the street its my girlfriends car and she would have to clean it Ray I have been looking around and so far the cost is making me look for a different car. It has pretty much sat for the last year, so it needs some love. I had a couple of days off and figured I would get it running again when I found the issue with the immobilizer. Apparently this is a common issue with these cars. I have already had to repair the ignition once and now I have to consider what would be the best option. If its going to cost more than $200 then I need think is it worth it to keep putting money into it when there are some nicer cars out there.

I have to assume that not all immobilizers are created equal. I had my JDM Subaru sit for two years with no car battery installed, and the engine started just fine when a battery was subsequently installed. Could there be more to the Honda immobilizer's problem than just being without power for "too long"?

NO no, once the little bastard starts the car, point the gun at him and tell him to get out of the car with his hands up, THEN have him explain HOW he started the car, THEN shoot him. You'll figure out how to do it, AND you won't have to clean up all the blood and broken glass out of the car. THINK, people!

It was the charging procedure and trying to "jump start" the car instead of just letting the charger do its thing. Apparently this is a known issue with this model. I guess you can corrupt the key data if you turn on the key or try to start the car under other than normal power levels. Yes not all of them are created equal.

Ah, good to know. Lambo nut FEB 04, 11:08 PM quote Originally posted by Patrick: I have to assume that not all immobilizers are created equal.

Just changing the battery in a 2000 something VW Beetle can cause a tow to the dealer due to immobilizer problems if you aren't careful.
