Keyless Entry Keypad Corroded - Not from the battery

[foxhead]

My keypad died recently, thought it was the battery, but found that moisture had gotten in around the buttons and corroded the circuit board. Again, the area on the board around the battery was clean...

I contacted PT with little results and have to have a "dealer" order me the whole set, actuator, wiring, and pad.. This is going to cost a fortune I'm sure...

I found a part number in LCI's catalog that shows just the keypad. It's made by Southco Industries.

Anyone ever successfully bought just the keypad? I am wondering if I can repair the circuit board?

It is really handy to get unlock the trailer, and was a selling point for the DW...

Any help is appreciated.

I have always dealt with the manufacturer when ever possible on all devices in the RV industry. The keyless entry was provided by Lippert. I had terrific help/parts/tech. info from their service people, although mine has died again. I believe these units will have to be redesigned, they are affected by moisture to easily.

I believe Prime Time has stopped using them until a more reliable unit is provided.

Curious to what your keypad looks like, we have two different keys on our rig and if i have to order two new locks maybe i just go with the keypad instead.

Where are you gonna order your door locks from ?

After I received technical data from Lippert I replaced the battery in the keypad, re-sealed the unit using silicon grease and have no problem for 3 years.
BUT, always a but, the keypad can be "blamed" easily when the door solenoid does not react. The keypad is the only easy visible component and gets blamed. I have found more often the contacts at the bottom of the door on the hinge side are frequently not making a good contact. These contacts feed the 12V to the transmitter and solenoid in the door. I have solved this issue by dabbing a small amount of "Carbon Contact Grease" on each contact. This grease is available from a Electrical/Electronic Supply store. Works Great ! I clean it off annually and dab some fresh grease because it picks up dirt during the year.

Keyless entry for over 3 years !! Great ! Love our Lacrosse !!

The keypad no longer lights up, and appears to have a corroded spot on the circuit board... I will try this suggestion though, just in case.

Here's a picture of where I think the corrosion is...


Thanks.
