Smart Door Locks: Fingerprint, Keypad, Card and App Types, Wi-Fi and Bluetooth, Battery Life, Backup and Door Fit
Smart door locks replace or add to the key with a fingerprint, a code, a card or a phone, and they record who opens the door. They suit homes, rental properties and offices where keys get lost or shared. The choice depends on the door, the power source, the backup method and the quality of the lock itself. This guide covers types, connectivity, battery life, door fit, safety and indicative prices. For other locks, see door locks in Pakistan.
Types of smart lock
Choose by how you want to open the door.
| Type | How it opens | Note |
|---|---|---|
| Fingerprint | Registered fingers | Fast, no code to forget |
| Keypad | Numeric code | Share temporary codes |
| Card or tag | RFID card | Good for offices |
| App and Wi-Fi | Phone or remote | Needs reliable internet |
| Combination lock | Fingerprint plus code plus key | Several backups |
Power and battery life
Most smart locks run on batteries that last months to a year, depending on use. Choose a lock with a low-battery warning and an emergency power input, so that a flat battery does not lock you out.
Mechanical backup
Keep a physical key or a code backup. Electronic parts can fail, so a mechanical override is wise. Store the spare key outside the lock.
Door fit
Check the door thickness, the latch type and the existing lock cut-out. Many smart locks fit a standard mortise cut, but some need a larger hole. See door lock types and design and the replacement guide.
Safety and privacy
Choose locks with encryption for app control, change default codes and remove old fingerprints. Check fire safety rules, since a door must open from inside in an emergency.
Where they suit
Homes, rental properties, offices and guest rooms benefit most. For access control with magnets, see electromagnetic door locks and automatic door locks.

Installation
A competent fitter can install most smart locks in an hour or two. Check the door alignment first, because a door that rubs will wear the lock.
