Do's & Don'ts of Choosing Codes for Access Control Systems, Springdale, Ohio

Access control systems used to be a simple lock and key, but as technology has advanced, so have the tools that protect businesses. These highly durable locks stop intruders—as long as they can’t figure out the code to enter. Here are some do’s and don’ts to selecting the right code for your PIN-based access control system.


Choose something short that’s easy to remember.

It’s important to choose a good code, but it’s even better if you can remember what the code is. Select a four-digit code randomly, or think about acronyms to help pick the right sequence. An acronym, like “I really like pizza,” would equate to IRLP. Using the letters on the keypad may be easier than remembering numbers.

Change the number quarterly.

Changing the numbers too often may becoming frustrating for your employees, and the numbers may start to meld together in their heads. Once every three months allows the employee to learn the new number, and gives them time to discard the past PIN. Changing it every week may be more secure, but be prepared to go to the door to let people in, because they forgot the PIN.


Choose something obvious.

Birth dates and the last four digits of your social security number are easy to find online. Stay away from any code that can be found on your Facebook page, Twitter account, or business website.

Keep the code in view.

Writing the code down on a sticky note and attaching it above the keypad gives everyone access to the new PIN. Also, only announce code changes to employees, and do so in person to avoid email tracing. Posting a code change on a door gives undesirables more information than they need to know.
