Having the OEM Trimark 60-650 door lock on our Class A's main door, I was very motivated to change it after reading too many stories about the main latch bolt breaking inside the latch/lock - inside the door.
Lucky for me this did not happen, but I did have issues when the outside paddle would bind...because it has an odd "metal on plastic" wear point that is on the outside of the lock body and exposed to the elements. Plastic - really?!
I checked the measurements and ordered Bauer EM (part #013-531) for our standard right side hinged door.
This design seems to be required by a safety law (Federal Motor Vehicle Safety Standard / FMVSS206) for the latch/lock to have the 2 large jam pins that make a mechanical connection to the frame at the strike plate.
I bought the lock from Dyer's RV who had the best overall price (sale plus shipping), it came in 3 days after order and was well packed. It installed exactly like the video below...SO SIMPLE...anyone could do it.
I highly recommend this mod for 3 reasons:
-The keyless entry is very nice, plus only 1 key when the battery is out.
-The Bauer EM is a perfect match for the old/flawed Trimark 060-650
-The strike plate does not need to be swapped (molding and frame work required) because unlike the improved / recommended replacement Trimark 060-1650, the Bauer EM has the same sized jam pins and identical strike plate as the 060-650.
