Hello,

I'm installing a Code Alarm CA671 into a 2006 Ford Explorer with the keypad. It seems that the CA671 is not sending a lock/unlock pulse to the Explorer on the first press of the transmitter. I counted and it takes 2 presses of the remote to unlock the vehicle, and 6 presses to relock the vehicle.

Both wires from the CA671 are connected correctly to the vehicle's lock/unlock wires and installed with diodes, but the CA671 doesnt seem to send a ground signal to the vehicle on the first press of the transmitter. When i manually send a ground signal to the lock/unlock wire in the vehicle it will lock/unlock with every pulse so i know its not the vehicle.

I have the manual arm/disarm and unlock switch sense wires hooked up to the vehicle to make the keypad work- does this have anything to do with the problem?

Is there a setting on the CA671 I should be using? Is there any trick to an install on a Ford Explorer?

Thanks in advance for your help!

Why do you have diodes in the lock wires? Where are they located? you don't need them and that may be your problem. If the alarm is definately showing an output everytime you are pressing the button, worse case senario you could wire up a couple relays to get a stringer negative pulse....

I use code alarm all the time and the remotes on some models suck you can press the button a few time with no response on the ca500 I would put a piece of cardbord in the remote between the backof the battery and the back of the case and on the ca650x there is nothing you can do the response from the remote sucks. On most of the code alarm I do When testing the triggers and I set the alarm off I will press unlock up to 15 times before it stops. I dont know what it is but Like I said before the respone time from the key fob to the alarm sucks. Im not sure what u can do you might just have to deal with it, it does suck.

I dont know if ur a code alarm fan but I hate the stuff just my opinion.

As far as the doides on the lock and unlock wires from the alarm, I seen door locks go up and down for no reason at all , at different times in the day on the explorer if a alarm, remote/start, or anything where you add locks was installed and when you add the diodes it stops.
