I just installed a new head unit as my car (96 civic ex coupe) came without a radio from the previous owner. Anyways my question is it at all possible to have keyless entry and alarm while still obtaining a oem key fob? Thanks in advance

 

Possible.....yes I've seen it done before.
Worth the time, effort for the results.....definitely not.

 

Get an aftermarket alarm instead. Keyless entry won't deter any thieves.
