Hi guys, I was looking to pick some brains in this forum to try and get my keyless entry to work again. The car is a 2000 civic ex, and used to have keyless entry. I still have the fob from when the entry was working, battery changed and lights up red when the lock/unlock/panic button is pressed. I just replaced the keyless entry module in the driver's footwell and the entry is still not working. I can't get either modules (the new and the origional) to go into programming mode. There are some modifications to the wiring by the ecu, it is running a jdm computer so it has a jumper harness and it had the CKF bypass trick done so the two ckf wires are spliced. I also tested all the fuses and they are working. I am STUMPED as to how to get these working again.
Appreciate the help!

 

keyless entry has nothing to do with the ECU. At this point, I would just ditch that idea and get an aftermarket keyless entry kit/alarm. I'm assuming the door does lock if you press the lock button on the door cards...right?

 

After the trying to replace everything but the fob, I bought a cheap one off amazon to try. Turns out the key fob was the issue. I was able to program it and it is working now! Thanks for the help @NVturbo

 

I was thinking it was your remote or you weren’t doing the sequence quick enough to get it into programming mode. Glad you got it sorted out.

 

Glad you got it working
