## When Should You Change Your Locks?

Ensuring your home or business is secure starts with your door hardware.

### Moving Into a New Home

You never know who has a copy of the old keys - realtors, contractors, or previous owners. Start fresh with new locks.

### Security Upgrades

Standard builder-grade locks are easy to pick or drill. Upgrade to High-Security or Smart Locks for better protection.

### Wear & Tear

If your key sticks, turns with difficulty, or the latch is loose, it's time to replace the hardware before it fails.

## The Big Question: Change vs. Rekey?

### Rekeying

**What is it?** We keep your existing lock hardware (handles/knobs) but change the internal pins so old keys no longer work.

**Best when:**

- Your current locks are in good condition.
- You want to save money on hardware costs.
- You want one key to open all doors (Master Keying).

### Changing Locks

**What is it?** We completely remove the old lock and install brand new hardware.

**Best when:**

- Your locks are old, rusted, or broken.
- You want to change the color/style of your handles.
- You want to upgrade to **High Security** or **Smart Locks**.
