We just upgraded to a keyless entry for our 2002 Discovery 38W (RVLock Atlas).
We have the OEM keyless entry that could be used by someone - I know these like all parts are fairly pricey so we thought we’d see if anyone wanted them. The top key-lock was loose in its cylinder so we taped it in place, but other than that it worked fine.
We would ship this to you for $50 plus shipping. Included is only the mechanicals shown in pictures. This does not include the hardware buried deeper in the door which runs the keyfobs, so you would still use your own keyfobs.
Currently in Oceano, CA, soon in Bakersfield.
