I use to have a viper 690xvr for my 04 lancer ES. I loved the auto lock feature (since I would always forget to lock my car) and the over 1 mile range of the two way remote. I could lock and unlock my car from a distance that I couldn't even hear the alarm chirp anymore.

Does anyone know if our cars are very problematic due to the chip in the key and imobilizer?

 

I believe an aftermarket alarm is possible. I think it would just replace the functions on your keys.

If you do go for one, look at getting one with a tilt sensor. Stops your car from being towed or stolen on a flatbed.

 

haha those are mainly meant for people trying to steal your wheels. a tilt sensor just makes the alarm go off when its tilted past like 10 degrees or so. if you have a flatbed and want to take it, you can, the alarm will just keep going off. its not like it makes the car attach to the ground lol

but if you are interested I could have an Avital 2100 system for sale including 3 sirens.
