Realizing a deadbolt is stuck and won't unlock is an unpleasant experience. However, you may be able to get it working again with a simple trip to the hardware store. Read this guide to learn how to lubricate a deadbolt lock and what your options are if it still won't open.

Choose a Silicone Lubricant

Unless you already have some on hand, you'll need to make a quick stop at your local hardware store to pick up some lubricant. A silicone lubricant that's designed for metal is best. Make sure to purchase one that includes the small straw that can be used to inject the lubricant into small spaces. You'll need it in order to lubricate the inside of the lock.

Application Process

With your lubricant in hand, put the straw on the inside of the lock, right where the key is inserted. Generously spray the lubricant into the lock, pointing up and down as far as the straw can go. Let a little time pass, then insert the key and try turning the lock. If it doesn't turn, spray some more lubricant into the slot and then give it another try. You can also spray the lubricant directly onto your key in order to get it deep into the lock. However, don't be forceful with the key, as you could end up snapping it off and ending up with a bigger problem.

Indoor Application

If you successfully get the lock open, head inside and perform this step. Remove the backplate of the lock with a screwdriver to expose the bolt inside the lock. Then, apply more of the lubricant to the exterior of the bolt. Open and close the lock repeatedly to thoroughly and evenly distribute it. You should feel the lock loosen significantly and become easier to turn. When it's appropriately loose, put the backplate back on, and you're finished.

For future reference, performing this step as maintenance is a good idea. Doing so should help to keep the lock from becoming stuck in the first place. Any time you feel that the lock has become a little stiff, spritz it with some lubricant.

Still Stuck?

If these steps didn't work and the deadbolt still won't unlock, you can try removing the lock entirely and replacing it. However, if you can't get indoors to access the screws that are holding the lock in place, you'll need to call a locksmith at a company like Locksmith  Services.

While this may seem unfortunate, you can rest assured that your locksmith will be able to quickly remove the lock from your door and get you back inside. Low-quality locks made out of poor materials are generally to blame for deadbolts jamming. Locksmiths carry high-quality deadbolts in their inventory, so the new lock you'll have installed will be unlikely to jam in the future.

Whether you fix your deadbolt yourself or have to call a professional, remember that choosing a high-quality lock and performing regular maintenance will help you to never encounter this problem again.
