OEM keyless from a newer car into my 91 Accord wagon

[invader_zim]

Ok so I already have the keyless entry remote and the Omron transponder box from an 03 Element. I was wondering if it it is even possible to wire this up so I have keyless on my car. I know I could get an aftermarket alarm etc. I just think it'd be cool to have an OEM key fob instead of some generic aftermarket one.

Is your wagon an EX that has keyless entry from the factory?

Those use a single wire serial communication bus. I have a feeling it is a standard protocol that ford and Chrysler use but Honda gives no info on it. To use it you need to translate serial data and build a circuit for what you want. Or you could get the interior fuse and use it since that where all the translation happens on the Element.

No, it's an LX.

You man the fuse box under the dash?

What your asking is NOT easy, and honestly not something id bother with. Modern OEM keyless units use a communication bus, as described. I dont even know anyone thats been succesful in doing this. Have you considered retrofitting the internals of a generic Keyless remote into an OEM one? moving switches around to fit a new look OEM remote will be alot easier than using an oem Keyless entry setup.

you could use one from a car that still uses standard wiring. i know a 97-01 Prelude alarm would work. Maybe s2k may work? ive never bothered though. you can buy OEM blanks off ebay, a generic keyless for $20, and then all youd need to do it is Remove the switch from the generic remote, using small gauge wiring Then wire the Switch to the original board, Then Either plastic weld or hot glue the switches in place.

much, much, MUCH easier than bothering with all this OEM keyless crap.

The only difference would be how the box under the dash looks.

Do you really care that much about a box??

I would suggest pulling everything out of a newer car related to the lock system that you can. While it is true that new cars use a CAN bus instead of the old method of turning on wires to communicate data the final result is it still controls a motor so as long as you have all the parts and a book for the car you pull the system from to wire everything back up correctly you should be okay.

I've never done this before but contemplating it.
