Any lock experts out there? I have been trying to get the lock on the back door of my van open for a few days. I've oiled it, put grease on the key and worked it in, but it will not open. Its the type with the key barrel in the handle. The barrel twists about 70 degrees and the handle had free play like it does when locked, but the key will not trun the full 90 degrees it need to open. All feels normal when wiggling the key in the lock and key goes in easily. The van has been sitting for a fair while and I thought it would just need some greasing, but been trying for days by wiggling key in lock with grease. Any thoughts?
