Keypad Lock Installation in Charlotte, NC

Mechanical keypad locks have no electrical components at all and function identically regardless of power. Electronic keypad locks are battery powered and operate independently of your home or building electrical supply, so a power outage does not affect them. Most electronic models provide a low-battery warning well in advance, and some include an external terminal on the outside of the door where a 9-volt battery can be touched to provide temporary power if the internal batteries are fully depleted before replacement.

Most residential electronic keypad deadbolts include a key cylinder on the exterior as a physical override. This is useful if the battery fails completely and you do not have an emergency charging option. Some models, particularly commercial keypad locks, are available in key-override and non-key-override configurations. We confirm whether a key override is included or available when recommending a model, and we cut and provide the override key during installation.

This varies significantly by model. Basic residential electronic keypad deadbolts typically store between 6 and 30 unique user codes. Mid-range smart locks store 30 to 100 codes. Commercial-grade keypad locks from brands like Alarm Lock Trilogy can store up to 2,000 unique codes with individual time-zone assignments and audit logging. We match the code capacity of the lock to the number of users you need to accommodate.

In most cases, yes. Standard residential doors in the United States are prepared with a 2-1/8 inch bore hole and a backset of either 2-3/8 or 2-3/4 inches. The majority of residential keypad deadbolts are designed to fit these standard dimensions and replace an existing deadbolt without any additional drilling. Commercial doors may have different preparations depending on the frame and door material. We verify the door prep during the assessment and confirm fit before ordering or bringing hardware.

Most electronic keypad locks include a lockout feature that disables the keypad for a set period after a specified number of incorrect attempts, typically three to ten failed entries. The lockout duration is usually 30 seconds to several minutes. This prevents brute-force code guessing. Some commercial models generate an alert or audit log entry when lockout is triggered. We configure the lockout settings to your preference during installation.

Yes. Steel commercial doors typically use a different door prep than residential doors and may require a commercial-grade mortise or cylindrical lock body with a keypad trim. We carry commercial keypad hardware from Alarm Lock, Dormakaba, and Schlage commercial lines suited for steel doors with standard commercial preps. If the door has a non-standard preparation, we advise on the drilling required and provide the complete installation including any new bore work.
