Cairn's lead residential technician since 2013
Marcus handles the locks homeowners use every day, from a front door that won't open to a house that needs new keys after a move. His work includes residential lockouts, rekeying existing cylinders, installing deadbolts and fitting smart locks.
He also trains new Cairn technicians during their six weeks of ride-along work before they take calls alone. That training covers the company's inspection, authorization, pricing and testing standards, not just the mechanical work.
- With Cairn Lock & Key since 2013
- Residential lock and smart lock work
- Six-week technician ride-along training

The standards Marcus works by
A house key, a deadbolt and a smart lock need different attention. Cairn follows the same basic checks before, during and after residential work.
Check who has authority
Before opening or changing a lock, the technician verifies photo ID and the customer's connection to the property.
Inspect before recommending
A sound cylinder may only need rekeying. A worn lock or misaligned door can call for a different repair.
Put the price in writing
After inspecting the hardware, the technician presents the full written price and gets approval before starting.
Test the finished door
Every supplied key is tested with the customer, along with the latch, deadbolt and door movement.
