The challenge
The builder's key had to go
The owners had moved into a newly built home in Centennial Hills. The locks were still set to the builder's construction key. They wanted to move away from that key arrangement and start with keys under their own control.
They also wanted keypad entry at the front door for family use. That meant fitting the smart lock, making sure the deadbolt moved without resistance and leaving the owners in charge of their access codes.

Keep the hardware, change the access
The recommendation combined a whole-home rekey with a front door keypad. Each part addressed a different way the family would use its doors.
Rekey the existing cylinders
Rekey five cylinders to retire the construction key. The new home offer takes $20 off 4 or more locks rekeyed within 60 days of closing or move-in.
Use one house key
Set all five cylinders to work with the same new key, reducing the number of keys the owners need to carry.
Add keypad entry
Fit a keypad smart lock at the front entrance and adjust the strike so its bolt can extend without binding.
Leave account control at home
Have the owners set their family codes and retain the administrator account themselves.
Four parts of the installation
The work addressed the mechanical keys first, then the keypad and door fit. The owners finished by taking control of the electronic access.
Change the cylinder keying
Rekey all five existing cylinders, retiring the construction key and setting them to accept one new house key.
Fit the keypad deadbolt
Install the smart lock on the front door, providing a keypad option alongside the household's mechanical keys.
Free the bolt movement
Adjust the strike to let the deadbolt throw freely instead of making the motor push against a misaligned opening.
Set up owner access
At handover, the owners set their family entry codes and kept the admin account. Cairn retained no codes or logins.
One key, family codes, owners in control
The finished work gave the household three practical changes to how it opens and manages its doors.
One key for five cylinders
The owners carry a single mechanical key for the rekeyed locks, with the former construction key retired.
Family entry by code
The keypad provides another way into the home, with codes the family can set and manage.
Control stays with the owners
The front door bolt moves freely, and the smart lock's administrator account remains with the household.
“Our new house still had locks set to the builder's key. Cairn rekeyed five cylinders so we could use one key, then installed the front door keypad. They adjusted the strike so the bolt moved freely. We set the family codes ourselves and kept control of the account.”
