I just replaced the CH-751 compartment door locks on our Sunseeker and it was very easy. A tip: measure the cam length of every
door, as one of ours was significantly different. Cost was $4.25 apiece for key, lock cam, nut, and the screw to hold the cam arm in place at RVLocksAndMore
, and you choose the key code. What we like about the new locks: the keys are double-sided so we can insert them either way, we got (optional) new keys that have LEDs to light the lock, and the keys can be removed from the lock when unlocked. We are considering replacing the main entry door to match the new locks too, which can be done for $20 (not keyless).
customer service is excellent. One call got a Return Authorization for the lock that didn't fit, discounted shipping on the replacement, and parts to help with an off-size cam arm. We are very pleased with that source and this simple mod.
