Here are a few things for you to consider before you purchase push button locks. If you are able to do your homework in advance and come up with the answers to these questions, or a firm decision on them, you will find it much easier when it comes time to go and buy your push button lock system.
Mechanical or Electronic Push Button Door Lock: Very generally speaking, mechanical locks are better for smaller situations, or to use with additional security locks. Mechanical locks require very little maintenance and they are built to last. They do not need battery or other electrical power in order to work. If you want to have more access options, you should look into getting an electronic push button lock.
Battery or Electricity: If choosing an electronic push button lock, you should decide whether to go for a battery or electrical lock. Most batteries usually last around two years before they need changing. If you choose an electrically powered lock, make sure it has a battery backup function so you can still use the door even if there is no electricity.
Right Opening or Left Opening: It is best if you purchase a lock that can be switched to open on either the left side or the right side. This gives you much more versatility when it comes to installing the lock on site.
Pairing Options: If you think you may need additional security added some time in the future, make sure that the push button lock that you install allows you to add on and pair it with biometric or card reading devices. While you may have to pay additional money for this, it is well worth it as it can make upgrading later to a more secure system easier, and less costly.
Basic Modes: Make sure that the lock includes such basic modes as passage mode which allows you to leave the door unlocked at times, and lock-out mode which allows you to restrict entry even by those who know the pin number for opening the door. Another useful mode is the key over-ride mode, which is important from a safety standpoint. In this mode, someone can gain access even without knowing the pin code.
User Codes: How many user codes will you need? Decide in advance. If you are not sure exactly how many, it is better to err on the side of getting a lock with more than you think you will need, rather than less or the bare minimum.
Keypad: If your lock will be getting a lot of heavy usage, look for keypads with a wear resistant coating. Even one used solely for a residence will, after time, wear patterns on the number pad if it does not have proper coating.
Ease of Installation: If you are going to install push button door locks yourself, look for one that is easy to install, and that comes with specific user friendly installation instructions. If you are buying an electronic push button lock, see if there is a possibility of a free installation? Some companies will offer that.
