I'm using the Trique kit on my 55 and it says right in the package that the handle push locks will not work with their kit. I do find that a huge annoyance and am trying to engineer a solenoid locking system to do the job. The biggest hinderance is devising a mechanical safety unlock in the event of a power failure. I always wondered why some guys put the locking mechanism on the cab and the pin on the door(backwards).....now I know why. It would be way easier to do the solenoid mount and adjusting as well as the mechanical safety on the stationary post as opposed to the moving door. On the up side, they are easy to install and look good and they do integrate well with the stock handles, at least on the mock-up assembly. I ordered new exterior handles with locks keyed the same to solve the exterior problem and I think I've figured out the keyless entry thing to my satisfaction but it will be a couple of months before final assembly and real testing. I'm actually glad someone is having trouble with/questioning the stock lock system because I've spent numerous days saying bad words and wondering why I didn't just buy new stock stuff and leave well enough alone.
