It is not uncommon for electronic locks on safes to last upwards of 10 years. However, it is important to keep in mind that the lifespan of an electronic lock can be greatly affected by the quality of the materials used as well as how often the lock is used. For example, locks that are made with higher quality materials and that see less frequent use will typically last longer than those made with lower quality materials or that see more frequent use. Additionally, proper care and maintenance of an electronic lock can also help to extend its lifespan.
