I have a 1996 civic ex coupe. I've checked the FAQ section on this topic but it doesn't help with my issue. I am wanting to buy a keyles entry remote for my car ( I just found out the car came with keyless entry) but the steps to program it, that are shown in the FAQ section, are for a factory radio. How do you do it with a aftermarket radio?

 

Unless the Previous owner hid the original radio, you no longer have Keyless entry. You will either have to get an alarm brain or find a keyless entry radio

 

I still have the factory radio. Any way I can put it in the car. And still run the aftermarket one?

 

It apparently can fit behind the aftermarket one if you work at it.

 

You will need one of these harnesses, it has an extra plug for the factory radio which you hide in the dash.
