I have a stock alarm on my honda accord and the keyless entry is about to have to be replaced. Can you buy another keyless entry off the internet and use that as your replacement of the existing one? I am not sure if you would have to copy the codes or how you could do it. If you know how or know an easy way to upgrade an alarm for cheap, let me know? I hate my keyless entry now bc I have to be within 15ft for it to work.
