Im putting a Sony head unit in a 98 civic, but it has a factory keyless entry/alarm sys. The brilliant Honda engineers put the chip in the factory radio. How do I retain the factory keyless system while using the Sony unit?

 

you have to get an adapter harness from a stereo shop that allows you to retain the factory radio. it is kept plugged in but is put down behind the dash. i had to do this on my 98 civic ex coupe. or you can just get an alarm with keyless entry and not worry about the factory radio. i did this later.
i install car alarms as well as i can hook up the adapter harness and put the factory radio in your dash. i got my adapter harness from premier auto sound 484-6822

 

good knowlage from CHAHONDA....one thing he forgot mention...........it can be a pain to sqeeze the factory radio under the dash........i recommend getting the alarm its the win win situation............

 

yea, im goin with the aftermarket alarm. I looked at it last nite and its just not worth it to try and fit my radio and all the other electronics up under the dash. Thanks guys!

 

how much ya find an alarm for?

i can do one pretty cheap!

 

i wanna get one and install it, but i want keyless and remote start on it. I dunno how much they run, depends on the model.

 

If you have any advice as to which company/model is the best, let me know!

 

viper 550 esp, very good alarm and has remote start also. 2 of my vehicles have this alarm

 

i really dont wanna spend over $150, know any cheap (but good) companies?
