Not Sure Which Door Lock to Buy? We Supply and Install It.

Door lock selection, supply, and installation for Denver homes and businesses.

Need a new lock but not sure what fits your door? You don’t have to figure out the brand, find the right parts, and hire a separate installer.

Mile High Locksmith helps you choose suitable hardware, supplies the agreed lock, and handles the installation. Whether you’re replacing a troublesome handle, changing the locks after a move, or adding keyless entry, start with the door you have and what you need it to do.

Call (720) 248-8087 to discuss your door and arrange service


You Know the Problem. You Don’t Need the Part Number.

“The handle is loose.” “The deadbolt won’t lock.” “The key works, but the code doesn’t.”

That is enough to start the conversation.

Tell us what happens when you use the door and what you would like to change. We’ll check the existing hardware and explain whether the job calls for a repair, rekeying, or replacement.

When new hardware is needed, we’ll help identify a suitable option before you spend money buying a lock yourself.


Choose a Solution for the Door You Have

Replace a Faulty Lock Without Guessing What to Buy

A sticking deadbolt, a loose handle, or a latch that won’t retract can leave you unsure which part needs replacing.

We’ll check the problem and explain what can stay and what needs to change. That includes situations involving front and back doors, the door leading to the garage, and interior doors such as a pantry or office closet.

Want to keep your existing handle or match the finish of your other doors? Let us know before selecting the replacement.


Change the Keys After Buying a Home

Moving into a house or condo does not automatically mean you need to replace every lock.

We can assess the existing locks and discuss rekeying where suitable, replacing worn hardware, or combining both in the same visit when the required parts are available.

Want one key for several doors? We’ll check whether the locks can be keyed alike. You don’t need an exact count or a list of models before calling.

Add Keyless Entry—or Address a Keypad That Stopped Working

Choosing a new keypad lock and fixing an existing one are different jobs.

For a new installation, tell us how you want to use the door. We’ll discuss suitable hardware and explain the features of the proposed model.

For an existing keypad problem, describe what still works. A working key with a nonworking code gives us different information from a door that will not open at all. We’ll check the setup before recommending replacement.


Update the Locks at Your Business

A storefront entrance, a metal back door, and an interior office door may need different hardware.

Tell us which doors need attention and whether you need working locks repaired, keys changed, or replacement hardware supplied and installed. We can review several doors together rather than treating every door as the same job.

For unfamiliar or specialty hardware, we’ll identify the setup before confirming the replacement and installation timing.

Buy the Lock and Installation Together

You can order the replacement hardware and installation through Mile High Locksmith instead of coordinating the purchase and fitting separately.

We help you work through the practical questions: Does the proposed lock suit the door? Can existing hardware remain? Does the replacement provide the features you need? What work is included in the installation?

The goal is a suitable lock installed on your door—not simply a box of parts for you to figure out.

Already bought a lock? Tell us the brand and model so we can check its suitability and discuss installation.

Know What Is Included Before Work Begins

Before approving the work, you should know which hardware is being supplied, what installation or repair work is included, and the price. For keyed locks, we’ll also clarify the keys included with the job.

Any visit or assessment charge will be explained when arranging service. Some hardware can be identified from photos; other setups require an on-site inspection. Special-order parts and return visits are discussed before scheduling the installation.


Start With a Call, Not a Shopping Trip

Tell us where the door is, what is wrong, or what you want to improve. There is no need to choose a lock or identify every part before contacting us.
