There are a number of factors that can help determine whether or not the locks to your office need to be changed. If your business has a high level of staff turnover, or you keep valuable merchandise on the premises, then issue of your security will require greater attention. Similarly, the level of security you require, relative to the company turnover and the type of locks you have presently, should all be taken into consideration. For example, a key that is stamped can’t be duplicated, and will need to be changed less regularly than a lock with a standard key. Digital office door locks are a good option, as you will only need to change the lock’s code as and when your staff leave or the code is forgotten.
