I came across this device that supposedly works for all cars with power locks. I comes with a whole wiring system.... but I'm thinking isn't there a remote system already in the car and I could just get a new remote set to it?

Know what I'm sayin!?

 

Remote System already? why would there be? All the locks are wired together, not locked/unlocked by remote signlas from the switch in your car. Newer accords have remote entry but since you want one im assuming you dont have one

 

LOL

i would just save some money and get some good alarm with every feature u can think off.
yes u can get the control for some accords and programm the control and it should work. watchout sometime if u configure the control wrong the locks start going nuts open closing for no reason lol

 

Any keyless entry on the market will work for you. If your car originally had keyless entry, and you just do not have the remotes then you can go to the dealership and order some. They will need to be programmed to your system though. This can get expensive throught t Honda so I would just get an aftermarket one. 99-129.00 installed is about par for them.
