How do you get your doors to unlock when they are stuck in lock position and you have tried to unlock them manually?

If your doors are stuck in the locked position despite manual attempts to unlock them, first ensure there is no debris obstructing the latch or lock mechanism. You can try applying graphite lubricant to the keyhole and gently wiggling the key to work it in. If that doesn’t help, consider using a hairdryer on a low setting to warm the lock, which may expand the metal and help it disengage. If all else fails, it may be best to consult a locksmith for professional assistance.
