Frequently Asked Questions

What is a keypad lock?

A keypad lock is a mechanical or electronic lock that uses a numeric code for entry instead of—or along with—a key. At National Lock Supply, we carry keypad locks for homes, offices, schools, and multi-user facilities where keyless convenience is essential.

What types of keypad locks exist?

The main types are mechanical pushbutton locks (battery-free), electronic keypad locks (battery- or hardwired), and wall-mounted keypad readers that connect to electrified hardware.

How do keypad locks compare to traditional mechanical locks?

Unlike deadbolts or cylindrical locks, keypad locks allow code-based access without rekeying. This makes them ideal for shared spaces or frequent tenant changes.

Do keypad locks require batteries?

Mechanical pushbutton locks do not. Electronic keypad locks are battery-powered or hardwired, depending on the model.

Are keypad locks secure?

Yes. Commercial keypad locks are tested to ANSI/BHMA Grade 1 or 2 standards. They also reduce risks from lost or copied keys.

Are they ADA compliant?

Yes, especially when paired with lever handles that require minimal force.

Where are keypad locks commonly used?

They are popular in apartments, offices, gyms, schools, and retail, where multiple users need access without carrying keys.

Can keypad locks integrate with key systems?

Yes. Many include a key override cylinder (SC1, KW1, SFIC/LFIC) for master key compatibility.

What finishes are available?

Satin Chrome, Satin Nickel, Oil-Rubbed Bronze, and Matte Black.

Why buy keypad locks from National Lock Supply?
