Coach keyless entry stopped working

[LandKKnight]

Our coach keyless keypad and keyfob just stopped working. It always worked before, perfectly. Now it seems no power to it at all. Also, the handle outside the door won't light up either. Are these related? Any ideas, anyone? I tried searching the forum but can't find the solution.
Thanks,
Linda

Ignoring that the door handle won't light which is bothersome, I understand that the key pad gets its power from some contacts near the bottom of the screen door. You might make sure that the contacts are clear and shiny.

Check fuses of course but don't forget the electrical connection at the bottom of the door, that's for the electric door button and probably the electric step too. If the door/switch alignment is off you might be loosing contact and break the circuit.

Ours has an intermittent issue. I believe its the contacts on the door. If I give the door a tap in the area of the contacts it starts to work again. The contacts are nice and clean. They are spring loaded, so I lubricated with silicone. Still have issue.

Linda I know you have an Isata and not sure this will be any help but I know on the Force there is a fuse under the entry steps. Just an idea.. Good luck

I have solved many problems with Contact Cleaner. I got a spray can at ACE. Spray it everywhere and work everything while it's still wet. Its worth a try.

I added dielectric grease to the contact too. Cut down on the contacts getting surface rust

Dielectric means "non-conducting." Might be better to use a graphite-filled, conducting grease, although you're probably finding that the mechanical scrubbing that occurs when the door is closed is sufficient to make good contact.

Are you sure about that? I have used it in electrical sockets and light sockets on vehicles for years. According to permatex most dielectric grease are conducive

Fuse for this is in the stair steps cable harness. A meter check/ test lamp (12v) at the contacts will verify if power is available. If no power at the contacts then check/replace the fuse near the upper part of the steps assembly. If you have power then clean the contacts and see if you have power at the keypad (press any key they should light up) If lights come on on the keypad then enter your passcode. If it locks but won't unlock ( or vice versa) then call challenger door. There is a known issue with the poplocks keypad. Talk to Arlen at challenger door.
