The U.S. Accord EX already comes with Keyless Entry/Security Alarm System; it is part of the Multiplex Control system. On U.S. models, additional remote transmitter can be purchased and programmed.

Honda TSB 98-011

Since you don't appear to be in the U.S., your Accord EX may not be exactly the same as the U.S. version and may not be so equipped.

With any aftermarket keyless system, features may vary and you would follow the manufacturer's installation instructions. In general, Honda door lock systems are negative trigger; so, you would hook up the aftermarket keyless entry system following their instruction for negative trigger door locks.

 

The Accord LX is different than the EX. Therefore, keyless entry or security system was optional on the LX.

If the car did not come with the dealer installed keyless entry or security system; located behind the left fuse box cover, there will be an unused 2P gray connector (LX only) with a Grn/Red wire and a Blk/Wht wire. The connector usually is partially wrapped in tape. You would following the manufacturer's instructions for a negative trigger door lock system and hook up the aftermarket keyless entry lock wire to the Blk/Wht wire and the unlock wire to the Grn/Red wire there.

Of course, there will be other wires to hook up; but, each aftermarket keyless entry systems may vary in features.

 

Big thanks to you Mr redbull.I am from Nigeria.I bought the car from a friend My security alarm and power door lock are still working and i saw an aftermarket keyless entry on the passenger side fuse box compactment.which was programmed with toyota remote transmitter.Each time i use the transmitter to lock the car,when i want to unlock it after few seconds,the alarm starts sounding.And the is no manufacturer name on the keyless entry module.Could this be fixed?Where is the factory installed keyless entry located?

 

The problem sounds like the aftermarket system causing an issue with the car's own factory security system. The Accord's multiplex system incorporates the driver's door multiplex control unit, driver's multiplex control unit (located in driver's side under-dash fuse/relay box) and the passenger multiplex control unit (located in passenger side fuse/relay box).

As I don't know how your aftermarket keyless entry was wired into car's system, the proper fix would probably be to disconnect/remove the aftermarket system and first try to diagnosis the factory keyless entry/security system.

 

ok thanks maybe i will have to look for a technician to check it out for me.I will get back to you.
Thanks
