Rekeying Explained

What Is Rekeying — And When Should You Do It?

Rekeying is one of the most important things a homeowner can do — and most people don't know about it. Here's everything you need to know.

Lock rekeying service DFW TX — pins, keys, cylinder Guardian Locksmith Smart lock installation DFW TX Guardian Locksmith

How Rekeying Works

Every lock has a cylinder with a series of small spring-loaded pins. When the correct key is inserted, the pins align at exactly the right heights — allowing the cylinder to rotate and open the lock.

Rekeying means replacing those internal pins with new ones of different heights. The lock cylinder stays in place — only the pins change. The result: your old key no longer works, and a new key is cut to match the new pin configuration.

Cost: Rekeying is significantly cheaper than replacing locks. We can rekey all your home's locks in one visit.

5 Times You Should Rekey Your Home

✓
You moved into a new home — you never know how many copies of the old key exist
✓
A roommate or tenant moved out — they still have a key
✓
You lost your house keys — especially if they had your address on them
✓
A contractor, cleaner, or dog walker had a copy and no longer should
✓
You want peace of mind without buying all new hardware
