Hello Mark. The only way to get replacement keys for a Curt 23518 hitch lock is if you happen to know they key number. The problem with this is the key number is printed on the key itself, so unless you happen to have the key number written down somewhere, you are out of luck. The only option would be to find a way to forcibly remove the lock. Either cut it off with a grinder or drill out the lock core until it comes off. Then you will need to replace it with a new one. We do not carry the 23518 but we do have the Curt Trailer Hitch Receiver Lock # C23519 which is the stainless-steel version.

@Peter Not that I am aware of. If yours is in need of replacement you will just need a whole new locking pin.

@Mathieu Hel Mathieu. It doesn't look like we ever heard back from Mark here but if your lock is attached to the car and the keys are gone the only option would be to drill out the lock core until it releases, or to cut the pin off with a hacksaw or angle grinder. Or get creative and find another fun way to remove it.

@Mike Hey Mike. Unfortunately the Curt 119 key isn't one we carry here. If I were you I'd try reaching out directly to Curt. They should be able to tell you how to get one.

There isn't a specific height from the trailer floor recommended to mount the E-Track. My gut feeling is that if 3 feet is too low and 4 feet is too high then 3-1/2 feet might be perfect. Another option is to mount E-track pieces vertically along…

Since your truck has a longer short bed at 6-3/4 feet and the nose of your Grand Design Reflection 226RK is tapered and it has an extended pin box you actually could get away with a fixed fifth wheel hitch instead of a slider which will save you a…

No, you will not need to do any modifications to the Curt Hitch - 2-1/2" #C96CR in order to fit a hitch pin. Since the C96CR does not come with a pin, it is always a good idea to have a locking hitch pin for extra theft-deterrence if you are…

Hey Greg, thanks for reaching out. Unfortunately, no, Bulletproof does not offer an option for a single 2-5/16" ball platform. They do a single 1-7/8" ball, but the 2" and 2-5/16" balls are only available as a dual ball.

Since you need the key CH505 you'd need the part #KEYCH505. Then for the striker bracket you'd want the part #UWS-SBRACKET.
