How Long Does a Keypad Lock Last? The Complete Guide to Durability and Maintenance

Keypad locks have become increasingly popular for both residential and commercial properties due to their convenience and enhanced security features. Unlike traditional keyed locks, these electronic or mechanical devices allow access through numeric codes, fingerprints, or other digital authentication methods. But how long can you expect a keypad lock to last before needing replacement?

The lifespan of a keypad lock typically ranges from 2 to 10 years, depending on several crucial factors. This comprehensive guide will explore what determines a keypad lock’s durability, how to maximize its lifespan, and when it’s time to consider a replacement.

Understanding Different Types of Keypad Locks

1. Mechanical Keypad Locks
