If your door lock suddenly jams, keep your cool, as there are a few practical tricks you can take to fix it without delay without calling a locksmith right away. First, کلیدسازی شبانه‌روزی سیار کرج check if the key is bent or worn. A worn-out key can cause the lock to stick. Use an alternate key if available. If the problem persists, move the key side to side while applying slight pressure. A subtle lateral movement can assist, allowing the internal tumblers to settle into place.

Next, apply lubrication to the mechanism. Opt for graphite-based lubricant, which you can purchase at any local hardware shop. Do not use spray oils including WD-40, because they attract dust and can make the problem worse over time. Apply a brief burst of graphite lubricant, then turn the key in and out multiple times to spread the lubricant throughout. This helps loosen any debris or rust that may be causing friction.

If the key won’t turn at all, refrain from using excessive force. Rough handling risks leaving the key lodged|, making the situation much worse. Instead, grasp the exposed portion with needle-nose pliers, and ease it free without sudden jerks.
