Common Reasons Keys Break Inside Locks
Keys can break inside a lock when the key is worn or bent, the lock cylinder is stiff, or the door is putting extra pressure on the latch or deadbolt. Using force when a key does not turn smoothly can cause the metal to snap and leave part of the key inside the lock.
Common causes include:
Did your key break off inside the lock? Don’t risk damaging the cylinder; call our locksmith for help instead.

When Should You Replace or Rekey a Lock?
Rekeying changes the internal configuration of an existing lock so old keys no longer work. Replacing a lock involves installing new hardware.
You don’t have to replace a lock just because it’s old. If it still works but you want to stop old keys from working, rekeying is usually the best choice. This is common after moving, losing keys, changing tenants, or when someone shouldn’t have access anymore.
We recommend replacing a lock if it’s damaged, worn out inside, hard to use, keeps sticking, or doesn’t give you enough security. Our locksmith will check your hardware first to see if rekeying or replacement is best.
For cars, key replacement and programming depend on the make, model, year, and security system. Some cars let us remove lost keys from the system, while others need a different fix.
Did you leave your keys with a contractor months ago and never get them back? We can rekey your lock without changing your hardware or damaging your door.
Compare Keyless Entry Options and Choose the One That Best Fits Your Property
Many people focus on the hardware’s price, but the actual cost is the time spent at the door whenever someone joins or leaves. The type of door matters, too, since many prewar apartment locks can’t accept a standard smart deadbolt. We check the fit first, then recommend the best option based on how often you need to change access. Here’s how the three main options compare on the most important points.
| Factor | PIN Code Lock | Fingerprint Lock | Mobile Access Lock |
|---|---|---|---|
| Hardware cost | $50 to $100 for a basic keypad deadbolt | $100 to $400, and the sensor drives the price | $130 to $250 for most Wi-Fi models |
| Time to open the door | Three to six seconds while you type | Under one second once the print is stored | Under one second by tap, longer through the app |
| Battery life | Often past 12 months, since nothing draws power idle | Roughly 6 months, as the sensor stays awake | Roughly 6 months, as the Wi-Fi radio stays awake |
| Adding a new person | Share a code by phone in seconds | The person must stand at the door to enroll | Send a pass remotely, even while you are away |
| Removing access | Change the code, then retell everyone else | Delete the stored print at the lock or app | Revoke instantly, with no visit to the door |
| Record of entries | Limited, since one code covers many people | Names each person by their stored print | Full log with a timestamp for every entry |
| During a Wi-Fi outage | Unaffected, because the keypad works offline | Unaffected, because matching happens on the lock | Local entry holds, but remote control stops |
| Fits older NYC doors | Some slim models suit mortise doors | Rarely, as most need a standard deadbolt bore | Rarely, though retrofit models exist for some doors |
| Suits you best when | Codes change rarely and cost matters most | The same few people use the door daily | Guests, cleaners, and staff rotate often |
Are you still changing your keypad code every time a cleaner leaves? Book an assessment with us and upgrade to a system that lets you add or remove access in seconds.
Why Older Pre-War Doors in Union Square Need Specialized Lock Repair
Many pre-war buildings in Union Square still have their original doors and mortise locks. These locks are built differently from modern ones and often need special tools and repair methods.
Years of use, layers of paint, worn parts, and minor shifts in the building can all affect how the lock and door operate. Instead of replacing original hardware when it’s not needed, we inspect the entire door and lock to identify the cause and recommend the best repair.
Pre-war doors usually also have a different mortise lock design. Unlike modern deadbolts, the cylinder is often held in place by a screw that might be hidden under layers of paint. We carefully remove and replace only the worn cylinder when needed, so we can keep the original lock and door whenever possible.
Is your pre-war door sticking or hard to lock? Call us, and we’ll figure out the cause before recommending a repair.
