Roy’s RV Tips – TriMark 030-0900 RV Entrance Door Lock Repair

The TriMark 030-0900 is a 2 lock system. It has a regular lock and a dead bolt built in.

I do use it if I am planning on being gone for a while or if I park in a place that I am not comfortable with the surroundings. One day when I opened the door I noticed that the deadbolt was crooked and was sticking out a little bit too far. When I touched it to check it out, it fell inside the door. I took the door apart and found that the actual deadbolt had cracked into 2 pieces. Upon examination it is easy to see how this can happen as it is made from cheap cast aluminum.

Not willing to put out that much money for a simple cracked deadbolt I decided to create a new one. There is a brass plate on the back of the lock that is riveted to the casting making it impossible to remove the metal rod that extends the deadbolt. However, I was able to remove the deadbolt by using the key to extend the deadbolt all the way out, then bending the rod up just enough to slip the broken deadbolt out. The closest home improvement store to me at the time was Home Depot. I went to Home Depot to try and buy a piece of flat stock that I could build the new deadbolt from. Nothing they had was thick enough so I had to use the MacGyver in me and be creative with something else. I was able to find a clamp that has a steel rod on it that was exactly the thickness that I needed and it was only $10.79. I quickly purchased it and headed back to the RV with the intention of creating a new deadbolt. Below is a picture of the clamp after I cut off what I needed.

I left the cutting outside in the rain and so far there has been no sign of rust. Armed with a hacksaw, dremel tool, a good metal file, vice grips and a power drill, I proceeded to remove everything that did not look like a new deadbolt. I was able to take advantage of the clamp itself by using it to hold it in place while I made all major cuts. Then I cut the length last and used the vise grips to hold it while I fine-tuned the new deadbolt. Below is a picture of the results.

roys rv tips 6I reinstalled the lock into the door and it now works perfect again. I don’t think that the new deadbolt will break any time soon as it is made of steel and not cheap cast aluminum.
