However, no door lock is completely immune from problems which could be caused by an accumulation of dirt and grime, as well as issues resulting from the weather.

Common Door Lock Problems


Warping is usually caused by fluctuating weather conditions, as doors and their frames can change shape due to the effects of heat and water. This may stop the locking points from engaging.

Seized lock

A lock is seized if you can insert the key but not turn it. This is likely caused by the lock being blocked with dirt. To unblock a seized lock, it will need to be cleaned and lubricated.

Damaged key

A new key might not fit a lock if it has been poorly cut or has rough edges that need to be filed down. Damaged keys could also get stuck in the door and snap if too much force is exerted while trying to turn them.

Slow lock

Slow turning of the key typically occurs when dirt or grime has accumulated in your lock over time. A stiff, slow turn could also lead to a key getting stuck in the lock.

Worn lock

Locks become worn over time if they are not properly maintained. Your lock could be faulty if the key only turns part way, or the lock catches or stops during unlocking. Also look out for severe tarnish, rust, or other visible signs of wear.

Door latch will not shut

A door will sometimes not latch if the latch bolt is not properly aligned with the strike plate on the door jamb. You may be able to see the misalignment, however it is best to hire a specialist to fix the issue.

What to Do with Broken or Faulty Locks

Check the key

Select a reputable and reliable key cutting service such as Banham to ensure high quality. If your key looks like it has not been cut properly, it could cause you and your lock a number of issues. However, if you’re confident that the key is not the issue, you can use a couple of simple product to lubricate the lock and clear it of debris.

Lubricating the lock

A squirt of dry lubricant will fix some minor door lock problems. Apply the lubricant following the instructions on the product and give it a few minutes to start breaking down any dust and dirt, then slide your key in and out of the lock to see how smoothly it turns. If there is no resistance, the issue may be resolved. However, if the problem persists then please call a professional locksmith.

Never attempt to fix door lock problems with oils which are unsuitable for home improvement. Substances like cooking oil and botanical oil will attract more dust which forms layers on the locking mechanism, and will leave you in need of a more serious door lock repair.

How to Prevent Wear and Tear on Your Locks

Keep them clean

The best way to avoid door lock problems is by keeping them clean. Simply use a damp rag to wipe the external surface of your locks to keep them free of surface dirt. Don’t use abrasive, chemical, or petroleum-based cleaners as these may damage the lock’s finish. We also recommend applying a dry lubricant to your door locks at least once a year.

Take care of your keys

Take care of any keys you have had cut for your lock, as these will typically wear before the lock does. Always try and cut duplicate keys from an original to prevent your key from getting stuck in the lock.

Keep an eye on your door

Keep an eye on the state of your door, which must always be properly hung to keep locks functioning. If it sags and is not within the frame, this increases pressure and could lead to door lock problems. You should also oil the hinges on a regular basis to prevent the door from slamming, which can damage the hardware and eventually leave you in need of door lock repair. If you’re having issues with your door, then we can provide a free, no obligation survey and give you an opportunity to discuss your options with a security expert.

Use professional locksmiths

Most importantly, make sure you rely on a dependable and professional locksmith to fix any serious issues your door locks may have. Though you may be able to improve the issue yourself with care and maintenance, significant lock problems will be most effectively resolved by Banham locksmiths who can replace worn parts with original lock components, reassemble and reinstall your lock for you.
