Just moved in? Cancel old keys and rekey your doors on-site

When you move into a new place, you don’t really know how many copies of the old keys are out there. Rekeying fixes that without replacing your locks. Mile High Locksmith® comes to your house (residential) or to commercial locations for businesses, rekeys the doors you choose, and cuts new keys (plus a few copies) during the same visit.

Move-in rekey: what we normally do on-site
1. We start with the doors you actually use
You show us the doors you want done and what your goal is (cancel old keys, simplify to one key, add keyless access on the main door, etc.).
2. We rekey the existing locks
We rekey your current lock cylinders so the old keys are canceled and only the new keys we provide will work.
3. We cut new keys and a few copies
Most move-ins need multiple keys right away. We cut the new keys and make a few duplicates during the visit.
4. Optional: add keyless entry on the main door
If you want a lock with code / fingerprint / camera / WiFi / Bluetooth access, we typically install it on the main door (or a commonly used side entry) and fit it to the existing door. If needed, we also align the rest of the standard keyed locks so your setup stays practical day-to-day.

Business move-in checklist (commercial)
For commercial properties and businesses, move-in rekeying usually focuses on the doors that control real access:
- Glass front door lock
- Back door
- Exit device lock
Typical goal: reset access after turnover
When keys have changed hands (staff changes, tenant turnover, contractors), rekeying resets access so old keys stop working and you control who gets copies moving forward.

Keyless upgrades during a move-in rekey
If you want to modernize access while you’re already doing a rekey, we commonly install a lock with features like:
- Code / keypad
- Fingerprint
- Camera
- WiFi
- Bluetooth access
We typically install it on the main entry (or a frequently used side entry), fit it to the existing door, and-if needed-match it with the rest of your standard keyed locks so you’re not stuck with a messy mix.

Questions people usually ask after moving in
I just moved in – can you rekey my front door?
Yes. We rekey the front door on-site so old keys stop working, then cut new keys and a few copies during the same visit.
Can you rekey the front door, back door, and garage door at the same time?
Yes. That’s the most common move-in setup for a house (residential). We rekey the doors you use every day and set them up the way you want.
I’m moving into a new business – can you change the keys on the glass front door?
Yes. Rekeying the glass front door is usually the first step for commercial businesses moving into a new space.
Can you also rekey the back door and the exit device lock?
Yes. A typical business move-in includes the glass front door, the back door, and the exit device lock – all handled in one visit.
After moving in, can I add a keypad lock instead of using only keys?
Yes. During a move-in rekey, we often install a keypad, fingerprint, or smart lock on the main door and keep the rest of the doors working with standard keys.
