Keyless Entry Lock Installation

Types of Keyless Entry Locks

Keyless hardware comes in a few distinct families, and the right pick depends on your door and your habits:

• Keypad deadbolts. A motor or thumb turn throws a standard deadbolt after you enter a code. Most include a key override cylinder as a backup.
• Mechanical pushbutton locks. These use a spring-loaded code chamber instead of electronics, so there are no batteries to change. They typically hold one shared code.
• Smart locks. These add Wi-Fi, Bluetooth, Z-Wave, or Zigbee radios so you can send codes remotely and check an entry log from an app.
• Keypad lever locks. A latch-only option common on offices and interior doors where a deadbolt is not practical.

What Installation Actually Involves

Most keyless deadbolts are built to fit a standard door prep: a 2-1/8 inch crossbore through the face of the door and a 1 inch edge bore for the latch. The backset, the distance from the door edge to the center of the bore, is either 2-3/8 or 2-3/4 inches, and most modern latches adjust between the two.

The step people underestimate is strike alignment. A motorized deadbolt cannot force a bolt into a misaligned strike the way your wrist can. If the bolt drags, the motor stalls, the lock reports jams, and batteries drain fast. A properly fitted lock throws its bolt with the door closed using only fingertip pressure. Door thickness matters too; most units fit doors from 1-3/8 to 1-3/4 inches thick without an extension kit.

Choosing a Lock That Fits Your Door

Look for an ANSI/BHMA grade on the box: Grade 1 is the strongest rating, Grade 2 a solid residential step up, Grade 3 the basic standard. For an exterior door, check the keypad's temperature range and weather gasket, since rain and direct sun are hard on electronics. If your door or frame is steel, a Wi-Fi or Bluetooth model may need its hub or your phone closer, because metal weakens the signal. Also compare code capacity: many keypads store dozens of user codes for family, cleaners, or dog walkers, while mechanical pushbutton models hold just one.

Setup, Codes, and Batteries

Most electronic models run on four AA batteries and flash or beep a low-battery warning weeks before they quit; swapping batteries and changing codes is safe to do yourself. Motorized locks also run a calibration cycle at install so the motor learns the bolt's full travel and its handing; skipping that step is a common cause of half-thrown bolts. Delete the factory default code the day the lock goes in, give each person their own code, and consider enabling the auto-lock timer if you tend to forget to lock up.

When to Bring In a Locksmith

A locksmith earns their keep when the door is not already prepped: drilling a fresh crossbore in a blank door, deepening a strike mortise, or correcting a sagging door that binds the bolt. They can also rekey the override cylinder so your existing key still works, and untangle pairing problems between a smart lock and its hub. If you are unsure what your door needs, call (916) 913-5080, describe the door and the lock you have in mind, and confirm whether the service can help before any technician is scheduled.

Frequently Asked Questions

Can a keyless lock be installed on a door that has never had a deadbolt?

Yes, but the door needs a fresh crossbore and edge bore drilled at the correct backset, usually with a boring jig to keep the holes centered and square. A hole drilled even slightly off ruins bolt alignment for good, since you cannot un-drill a door. This is a job worth handing to a locksmith, who can also cut the strike mortise in the frame so the bolt seats fully.

What happens if the batteries die while I am locked outside?

Most keypad deadbolts include a key override cylinder, so a standard key still opens the door. Some models also have two small terminals under the keypad where touching a 9-volt battery powers the lock long enough to enter your code. Mechanical pushbutton locks avoid the issue entirely because they have no electronics. The best habit is swapping batteries as soon as the low-battery warning starts.

Can my existing house key still work with a keyless lock?

Often, yes. Many keypad deadbolts ship with an override cylinder that a locksmith can rekey to match your current key, so one key runs the whole house while the code handles daily use. Whether that works depends on the keyway, the cut pattern of your key, and the cylinder type the lock accepts, so mention your lock brands when you call.
