Door lock issue - new key or lock?

[fitzgemman]

The first thing to do is spray the mechanism with silicone spray and take the key out gently, taking your time. If this method does not work, the key should be clamped with pliers and loosen slightly. After that spray, a little fluid again and carefully turns the key again. My advice: after spraying, you should move the key a little bit to maximize the distribution of grease, wait about 20 minutes and then take out the key. If you succeed, you need to change the caster or the lock. Otherwise, the situation could happen again. If there is no problem when the door is open, but when it is closed, the key gets stuck, the door frame must be bored out. For this purpose, you can use a grinder, drill, or file, but in any case, it is best to call a locksmith from https://mylocallocksmithtx.com/grand-prairie/, who will do everything himself.
