PALOMINO PUMA 25RLSS – Entry Door Lock Replacement

Some repairs on an RV are DIY-friendly. Others involve propane, 120-volt shore power, or structural load-bearing components where a mistake has real consequences. Part of my job is knowing which category a job falls into — and being honest with owners about the line between a competent DIY fix and one that needs a professional on site. An entry door lock replacement on the Palomino Puma 25RLSS sits firmly in the DIY-friendly column — but that doesn’t mean it’s without its quirks, and a botched install means you’re either locked out of your rig or, worse, can’t lock it at all while you’re camped somewhere unfamiliar. I’ve been called out to enough rigs where someone forced the wrong hardware or stripped the latch mechanism trying to muscle through it without the right guidance, so I put this walkthrough together to help you get it right the first time.

The WELLUCK Lock That Actually Fits the Puma 25RLSS Door Frame

The entry door lock on a Palomino Puma 25RLSS fails in two modes: the paddle deadbolt stops turning smoothly, or the latch mechanism gets stuck partway, leaving you unable to lock the door from inside or out. The WELLUCK replacement is the direct bolt-in that accounts for the Puma’s specific door frame depth and mounting hole spacing.

What works

• Paddle engagement is smooth and positive—no binding halfway through the turn, and the deadbolt seats fully into the strike without forcing.
• The zinc alloy construction doesn’t require a full door seal replacement; mounting holes line up with factory drilling on the Puma, so you’re not drilling new holes through the door skin.
• Comes with two working keys and a spare, so you’re not stuck with one key or waiting for a locksmith to rekey the entire rig.

What doesn’t

• Amazon shipping is unpredictable—I’ve waited 10 days for this part to arrive while stuck at a campground, so order early if you’re on the road.
• The interior trim ring is plastic, not aluminum like the original, so it can crack if you over-torque the mounting bolts or if someone yanks the handle hard.

I second-guessed myself halfway through the old lock removal because the new lock’s exterior face seemed slightly thinner, but it seated perfectly once the door frame was clean and the strike was properly aligned.
