Smart Lock Installation Reference
Why this reference exists
Smart locks (electronic, app-controlled, keypad) are the fastest-growing residential lock category. Customer pays installed; locksmith earns in labor on each install. App setup, integration with smart home, family access management create recurring service revenue. This is the working reference.

Pre-install survey
Door measurements:
- Backset (distance from edge to center of bore): 2-3/8" or 2-3/4" standard
- Thickness: 1-3/8" to 1-3/4" typical (smart locks fit range)
- Bore size: 2-1/8" standard
- Latch bore: 1" standard
Most smart locks fit standard doors. Specialty doors (thick fire-rated, narrow stile) may need different model.
Door fit:
- Door + frame square + plumb
- Latch + strike align
- Existing lock condition (replacement OR new install)
Wi-Fi check:
- Smart lock needs reliable Wi-Fi at door
- 2.4 GHz required; smart locks do not join 5 GHz networks, so a combined-band router may need the 2.4 GHz band split out or made visible
- Speed test at door before quote
- Weak signal = add Wi-Fi extender

- Heavy use
- Wi-Fi reconnection cycle if signal weak
Door binding:
- Out-of-square door / frame
- Latch + strike not aligned
- Adjust strike or shim
Customer locked out:
- Battery dead
- Use physical key backup
- App password issue → customer service support
Code not working:
- Code disabled or removed
- Customer entered wrong
- Lock factory reset cleared codes
Customer education
For new install:
- App walkthrough (master account)
- Family member adding
- Code creation (permanent + temporary)

Most customers comfortable after 30-minute briefing.
Common pitfalls
- Poor Wi-Fi at door: smart features unreliable
- Customer's old door / frame issues: lock doesn't operate smoothly
- Wrong backset / bore size: doesn't fit
- No key backup mentioned: customer locked out
- App password forgotten: customer locked out of administration
- Battery dead during outage: same as forgetting key
- Family member added incorrectly: can't enter

Recurring revenue
After install, service contract:
- Annual battery check + replace
- App password reset assistance
- Family member updates
- Quarterly check-in (manageable for high-touch clients)
Price it as a flat annual or monthly monitoring fee. At 50 to 100 customers that fee becomes a recurring line worth more per year than the install revenue it came from.
Warranty registration
Most smart locks include manufacturer warranty:
- Schlage: limited lifetime mechanical + 5-year electronic
- Yale: 1-year electronic + lifetime mechanical
- August: 1-year typical
- Kwikset: limited lifetime mechanical + 1-year electronic
Register at install; preserve warranty.
Customer-facing emergency
If customer locked out:
- Ask what changed. Dead battery, forgotten code, phone lost or dead, app not connecting, or the lock stopped responding entirely. The answer picks the fix and often avoids a truck roll.
- Physical key override first. Most deadbolt-replacement smart locks keep a keyed cylinder. If the customer has the key on them or in a lockbox, the job is over.
- Emergency power. Schlage-style units take a 9V battery held against the exterior contacts; some newer designs take a USB power bank at an external port. That wakes the lock long enough to enter a code. Every customer should be shown this at install and should not be learning it on the doorstep.
- Backup code. The keypad code works locally even when Wi-Fi, the hub, or the app is down. If the customer only ever used the phone, this is the moment they find out why you insisted on setting a code.
- Another authorized user. Spouse, roommate, or family member with app access can unlock remotely if the lock is still online.
- Manual override from inside, if anyone is home or if a secondary entrance is accessible.
- If all of that fails, it is a standard lockout call. Pick or bypass the mechanical cylinder if there is one; otherwise it is a drill-and-replace of the cylinder, and the electronics usually survive. Verify identity and authority to enter the same as any other lockout, no exceptions because the customer sounds convincing.
Tell every customer at install: keep one physical key off-site (neighbor, car, lockbox), set a keypad code even if you plan to use the phone, and replace batteries on the first low-battery warning rather than the last.
