Keypad door locks are designed to be opened by entering codes, so they are limited at certain times.
For example, when the power goes out, or when you forget your code, you can't successfully enter your password and face being locked out by your own door lock.
Is there a way to unlock the keypad door lock without a code? Signstek can do that.
Signstek features an alternate keyhole that allows you to unlock even when you can't enter a code.

One more keyhole

Keypad door locks do not usually have a keyhole, which is the biggest difference between them and mechanical door locks.
Signstek, however, took into account the needs of some customers and, as mentioned above, added a keyhole to our keypad door locks. In this way, our keypad front door locks have the features of both keypad locks and mechanical locks, but the price is still the same as regular keypad locks.
When you forget the entry code, you can use the spare key to unlock the door. When you forget to take the key, you can enter a code to unlock the keypad door lock. Have two strings to your bow to ensure that you can unlock the lock smoothly whenever you want.
In Signstek online store, the keypad door locks with spare keyholes including ST-668D electronic touchscreen keypad deadbolt lock, ST-668 Plus touchscreen keypad door handle, PLU331 electronic keypad deadbolt lock and PT-R0S00 electronic keyless front door lock are equipped with spare keyholes, among which ST-668D, PLU331 and PT-R0S00 spare keyholes are exposed.
The ST-668Plus touchscreen keypad door lock hole is hidden inside the door handle, which requires the door handle to be removed to see, reducing the possibility of being picked lock, to a greater extent to ensure your family security.
