Hi
A mortice lock on an external door which I hardly ever use has become seized. I bet the problem is corrosion.
Anyway I've found out because now I want to use the door :)
I'm wondering if anyone here might be able to assist with some suggestions to free up the lock?
Thank you.
If siezed whilst unlocked then remove and dismantle
If locked small angle grinder and 3 mm metal cutting disk between the door and the frame to cut through lock bolt then fit new lock

Sometimes the door or the frame distorts jamming the lock bolt against the edge of the keeper/striking plate. Try pushing/pulling/lifting the door as you turn the key.
WD40?
the lock can them be removed
Tony
Spray in WD40 (including a bit around the bolt and strike plate) and leave an hour, put key in and try to open it. Don't use too much force (especially if you only have one key). If lock doesn't open spray in more WD40 and leave overnight. Repeat morning and night until it opens or you decide more brute force methods are needed.
The last jammed mortice I had, that wasn't an option....there were hinge bolts!
The message from patrick j contains these words:
I have a mortice lock that is a bit temperamental and jams when I try to unlock it but I have found that the reason it jams is that when last locked the levers didn't quite complete their full movement so if I start by turning the key the wrong way I can then unlock the door. A long shot I know but it is just possible you do have the same problem.
gentle hammer taps might help break up any corrosion, but its easy to damage the lock.

I got locked in our downstairs lavatory because the spring broke on a cheap 3-lever mortice lock (With a permanent "Bathroom" style turnkey). This had permitted the deadbolt to slip sideways so it could not be retracted back into the lock.
I got out when my son passed me a knife under the door which I used to align the bolt which was visible from my side so it could be unlocked.
Other experiences with mortice locks which won't unlock incuded Chubb
7-lever mortice lock which occupy the same outline and profile as their 5 lever locks, the levers just being that much thinner, *Hence they wear*, eventually the key no longer reliably fits, and the locksmith said his customers *always* disregard the minor warning difficulties until they eventually get locked right out.DG
A Huge Thank You for your advice I had this problem with my inner front door to my flat and could see a major bill looming up then i Prayed about it to GOD... and HE Directed me online to find this helpful site and then i sprayed the WD40 ...ALOT, BOTH SIDES (Lucky i have a back door as i live in a ground floor flat) then i went in search for my mallet hammer and proceeded to vent my frustration on the area where the bolt is while tryng to turn the key and then it gave and turned...WOW CHUFFED TO BITS TO SAY THE LEAST...and the bolt got sprayed with WD40 several times while i turned it back and forth, just to make sure that everthing was well lubricated, as i don't want a repeat! Thank You Again.X

Take your imaginary sky fairy friend and shove it where the sun don't shine.
The DEAR ALMIGHTY FATHER GOD/DEAR LORD JESUS CHRIST/DEAR HOLY SPIRIT will now proceed to evaporate the volatile solvent in WD40 and your lock gum up and you'll be back where you started, or worse. Be interested to hear what you have to say about him then. Should have used graphite powder.

I fear it was in fact Extreme Unction in that can and your lock is headed for certain death. On the positive side, the church pretty much abolished Limbo. Sadly, both Mumbo and Jumbo persist.

I didn't realise any of the Marx brothers were still alive.

Don't mention penetration, even obliquely. She'll be serving a pennance for weeks for just reading your post.
