One Last Keyless Question

[bt3100]

Thanks for all of the help so far.

1994 LS 400 had a few issues that I have fixed, only one left is the following.

The keyless entry did not work at all when I bought the car.

Removed aftermarket alarm and replaced batteries in remotes.

Now the remotes lock the doors, however they do not unlock the doors???

Any ideas?

I checked the wires that were tapped for the alarm, all are fine.

If I ground a wire to door unlock lead it unlocks, if I ground a lead to the door lock lead it locks.

Any advice?

Thanks again,

Joe
