Locking products can look nearly identical while differing in cylinder length, cam orientation, mounting style, keying and other important details. Providing application information early can reduce unnecessary back-and-forth.
Identify the Equipment
Tell us what the lock is installed on—cabinet, enclosure, vending machine, fuel dispenser, vehicle, kiosk, panel or other equipment.
Share the Existing Lock
Include manufacturer markings, a known part number, photos or any information available from the current lock.
Include Measurements
Cylinder length, mounting-hole dimensions, cam measurements and door thickness can be important when identifying a replacement.
Explain the Security Need
Tell us whether the goal is simple replacement, increased pick resistance, restricted keys, electronic access or stronger physical security.
Provide Quantity
Approximate quantity helps determine whether the request is a replacement, recurring product need, OEM requirement or larger deployment.
Describe the Keying
Let us know whether locks need to be keyed alike, keyed differently, master keyed or incorporated into a controlled key system.
