M1842 Posted April 2 Share Posted April 2 This is a silly question maybe. But when I unlock the trunk on my 55, the cylinder just turns and doesn't spring back when I stop turning and let go. It just stops where I leave it. To lock the trunk, I close the lid and I turn the lock cylinder the opposite way. I don't recall seeing anything in the owner's manual about this and its certainly not how any of my other cars (going back to the late 60s) have functioned, except for my 51 Chevy. Is there a broken spring in the lock or is this just normal operation? Is this something that one finds on well used (or abused} old cars.

JohnD1956 Posted April 3 Share Posted April 3 Have you lubricated the lock mechanism and it still acts like that? You could try some brake cleaner spray in there to free things up. and then some appropriate graphite lube. I'd use the liquid form of lubricant. 2 Link to comment Share on other sites More sharing options...
Frank DuVal Posted April 3 Share Posted April 3 Usually there is a spring wound around the lock mechanism. If this is not there, you need one. See the leftmost lock in this picture: https://www.jegs.com/i/JEGS/555/18115/10002/-1?gad_source=1&gclid=EAIaIQobChMImoSd65-lhQMVOEhHAR2AAwLuEAQYAiABEgICf_D_BwE That spiral looking spring on the end away from the keyway. If the spring is there, then lubricate. I like Lock-Ease. Others like dry powdered graphite, but just a little! it is easy to puff too much in. Most locksmiths warn against using WD-40. TriFlow is used by some also. 3 Link to comment Share on other sites More sharing options...
M1842 Posted April 3 Author Share Posted April 3 Well, checked the back of the cylinder and saw the coil spring. I hit the lock with brake clean and then some silicone lubricating spray and it works again! That must be the easiest thing I have fixed on the car. I will look for the products mentioned above to lubricate properly. Thank you for your help, John and Frank! Mark 2 Link to comment Share on other sites More sharing options...
