When you install an aftermarket alarm system that has a built in immobilizer -- which I believe all Viper and Clifford systems do -- do you:

1. Disable the immobilizer from Honda

2. Disable the immobilizer from the aftermarket alarm

3. Have BOTH the immobilizers installed?


When looking for an alarm, some stores are telling me that I have to leave a key inside the car (and hide it where the alarm unit will be stored). Either I have poor technical knowledge, or they just didn't explain why that needs to be done, but it just sounds like they are going to disable the immobilizer from Honda permanently through the use of a key. If that's the case, then wouldn't it make more sense to just keep Honda's immobilizer (since it's not bad anyways, and just save some installation cost??) and not wire in the immobilizer from Viper/Clifford?

Also, does anyone know if you can wire an OEM alarm's hood switch to an aftermarket alarm?

Thanks.

P.S. I will not be installing the alarm myself. And the only reason I want an aftermarket alarm as to OEM alarm is so that I can wire a 2-stage shock sensor (I think you can only jam in a single-stage shock sensor to OEM alarm?) and a backup siren.

 

The only reason you would need a key in the car is if you are installing an alarm with remote-start. Also, the factory immobilizer stops the ecu from running the engine (prevents fuel, spark, etc.). Aftermarket alarms have starter kill. No reason you can't have both. I don't think there is any way to permanently disable the factory immobilizer unless you: 1. hide a key in the car withing range of the immobilizer receiver, or 2. get a standalone ecu.

 

Will,

Thanks for the info. Now that I checked the websites, you are correct that those include starter kills and not immobilizers. Also, I'm not looking to install the remote start feature anyways (don't see why I'll need that on a manual tranny in my situation. That'll make life much easier then.
