Key Replacement in Baltimore Starts With the Key You Need
Baltimore has about 297,571 homes, so a key replacement request can mean a car key, a home key, or a key for a business. Call and tell us what the key is for, whether it is lost or damaged, and where you are. If you’re near I-95, I-83, or US-40, sharing that can help us understand your location.
We provide mobile key replacement and come to your location. For a car key, we can make a new one on site when all keys are lost. We also have a shop; call before going there so we can discuss whether your particular key should be handled at the shop or at your location.

Three Signs You Need Key Replacement in Baltimore
Your only key is lost
If you can’t find the key for your car, home, or business, tell us what it opens and where you need help. When all car keys are lost, we can make a new car key on site.
The key is damaged or worn
A key that is bent, cracked, or no longer works reliably may need replacement. Describe what happens when you use it so we can understand the issue.
You need another working key
If you need a replacement because you no longer have a usable copy, tell us whether it is for a vehicle or a door. The key’s purpose helps us identify the service you need.

Baltimore’s Housing Mix Makes the Door or Entry Important
The median Baltimore home was built in 1947, and 82% of homes were built before 1980; 9% were built since 2000. Those figures don’t identify what key or lock a particular property uses, so tell us whether you need a key for an apartment, a shared entrance, or a single-family home. With 48% of homes owner-occupied and 15% detached single-family homes, being clear about the specific door or entry helps us understand whether you need one key replaced or keys for more than one access point.
What Affects the Key Replacement Estimate in Baltimore
- What the key opens — A car key, house key, and business key are different requests. Tell us what the key is for so we can discuss the right service.
- Whether the key is lost or damaged — Let us know if you have a damaged key to examine or if every key is missing. For cars, we make a new key on site when all keys are lost.
- Where the work should happen — We come to you for mobile service and also have a shop. Call to discuss which setting fits the key you need replaced.
- Applicable service call or discount — The listed $15 service call applies to car, house, and business lockouts and service calls; it is not a listed key replacement price. Eligible veterans and active military, seniors 65 and older, and police, firefighters, EMTs, nurses, and other health workers receive 10% off. One discount applies per job, and discounts do not apply to the $15 service call.
