If you’ve got a business with a card access control system, you should know how Daylight Savings Time can affect your system.

Daylight Savings Time lets us fall back an hour, but your card access system may do the same. Below we explain how to prevent that from happening and what to do if the clocks in the controllers don’t fall back like they should.

Keep your card access software on.

Many businesses don’t keep the software on all the time, but this weekend is a good time to make sure it’s turned on. That way, when the clocks roll back, your software will update the clocks in the controllers.

If you’re card access control system software is not on this weekend, your clocks won’t adjust and your employees may be locked out until an hour later than the start of business. Also, your doors could remain open until an hour after the close of business.

Not having the times adjust in your card access system can be an annoyance and disruptive to your business operations, so it’s important to do what you can to prevent it.

What to do if your card access control software is not on during Daylight Savings Time

If your software is off during the switch or the clocks haven’t adjusted, turn the software back on and consult your security system provider about your next steps. What to do after that can depend on your software version.


Daylight Savings Time doesn’t have to have a negative impact on the card access control system at your business. Make sure your software is on this weekend and enjoy your “extra” hour!
