Ice-Pick Protector: How to spot and reinstall the anti–ice-pick collar inside the housing for maximum security.
Shim-and-Follower Rekey: No key? No problem. We shim open this five-pin cylinder, toss out the old wafers, and set up a new bitting.
Key-Cutting & Pinning: Using an ITL code machine and a Schlage-specific lab kit, we cut to code 3-2-5-4-1 and rebuild the plug with top pins, bottom pins, and springs.
Reassembly Tips: The critical 45° turn, preventing pin-and-spring ejection, and proper torque on end-cap screws (finger-tight + two clicks).
Final Install: Snug mounting screws, correct tailpiece alignment with the bolt out, and complete lock/unlock tests before we leave.

Why Choose the Schlage B660 Deadbolt?

The Schlage B660 Deadbolt is a highly sought-after lock due to its versatility and reliability. This heavy-duty, single-cylinder lock boasts a one-inch deadbolt and is commonly found in hospitals and school boards. Its design accommodates a variety of keyways, ranging from the Schlage C-series and SC1 (classic) to the Everest C123 and even the Primus series, making it adaptable to almost any security requirement.

Tools and Preparation

Before starting the rekeying process, ensure that the bolt is out and keys are removed. The process involves removing the thumb turn secured by two bolts and extracting the cylinder. Inside, an ice-pick protector enhances security, so confirm its presence when reinstalling.

Steps to Rekey the Schlage B660 Deadbolt

Cylinder Removal:
- Take out the cylinder from the housing using an end cap removal tool. Remove the end cap, spring, and retainer pin.
Shimming and Keying:
- If no key is available, a five-pin shim method is used despite the six-pin cylinder configuration. Insert a shim, then use a blank key to adjust the pin configuration.
- The code for keying in this example is 3, 2, 5, 4, 1, using a lab kit specially designed for Schlage locks. This kit comes with extra components like end cap springs and wafers.
Key Configuration:
- Carefully arrange the pins: rounded side down, tapered side down, flat side up, in the sequence 3, 2, 5, 4, 1. Ensure all pins sit flush for a perfect cut.
Reassembly:
- Mark the front of the cylinder for easy positioning. Insert the key at a 45-degree angle and turn it gently. Use your thumb or index finger to control the key as you extract it to avoid losing pins or springs.
- Reinstall the spring and end cap pin, and secure with the end cap removal tool, ensuring it’s finger-tight.
- Test the key – it should turn smoothly. If it doesn’t, adjust the tightness as needed.
Final Installation:
- Confirm the bolt is extended before placing the cylinder back into the housing. Reinstall the deadbolt bolts, starting them by hand to prevent cross-threading, and finish with a snug (not overtight) fit using a screwdriver.
- Validate the functionality—lock and unlock using the key, ensuring the process is smooth for both you and the customer.

Locksmith Pro Tips:

Always retract the bolt first—saving you headaches from misaligned tailpieces.
Mark the “front” of the plug and cover with an “X” so you never install it backward.
Lightly snug mounting screws; over-tightening can stress the housing.
