Hey guys I have been reading this forum a little bit and have searched through posts about keyless entry installations. I have a 1999 Civic LX Sedan that does NOT have keyless entry on it. I would like to install a keyless entry system on the car but I have been reading that you have to have the stock head unit to install a keyless entry system (at least on some models?). Is this true for the 99 year Civics? Also, what kind of keyless entry systems would you recommend? I don't need an alarm, and am looking to spend less money than more on this system. Is the installation difficult?

Thanks.
