If your door lock suddenly jams, don't panic, as there are multiple easy solutions you can take to resolve the issue quickly without spending money on service. Examine the key for signs of wear or deformation. A worn-out key can prevent smooth operation. Use an alternate key if available. Should this fail, lightly rock the key as you turn. Gentle oscillation often realigns the pins, helping the pins inside the lock align properly.

Next, clean and oil the lock. Opt for graphite-based lubricant, which you can get from a home improvement center. Avoid using oil-based products like WD-40, because they collect grime and exacerbate jamming. Spray a small amount of graphite into the keyhole, then insert and remove the key several times to distribute it evenly. This helps break up trapped particles or corrosion that may be restricting the mechanism.

If the lock is still stuck, check the door alignment. A door that has moved from settling or wear can put pressure on the lock mechanism. Try lifting the door slightly as you turn the key, or move it slightly side to side. This can free up the deadbolt and allow it to move more freely.

If the key won’t turn at all, never pry or twist aggressively. Applying too much pressure may snap the key|, making the situation much worse. Instead, grasp the exposed portion with needle-nose pliers, and withdraw it with steady, gentle motion. In case the key fragments inside, کلیدسازی شبانه‌روزی سیار کرج you may need professional help, but you can insert a straightened paperclip or sewing needle to eject the shard through the keyhole’s rear opening.

Finally, if none of these methods work, allow internal parts to relax. Sometimes the tumblers and springs just need time to relax after being stressed. Return after 10 minutes with a new key and fresh graphite. Scheduling periodic lock care is the most effective long-term strategy to avoid future lock issues.
