keyless entry not working.
My keyless entry in the driver side does not work, all other doors work perfectly.
I disassembled the handle to check the 3 wires, all 3 are in good condition and have no breakage.
Where should I look for the problem?

I'm already looking for a new Used handle, not quite easy to find, but ....

BTW can I change the handle from outside, or do I need to remove all inside door cover ?

Thanks for your reply.

No wonder why my keyless entry did not work. Thanks for the great input.
