When you move into a new home or want to improve your security, one of the first questions is: “Should I rekey my locks or replace them entirely?” The answer depends on your situation, but understanding the difference can save you hundreds of dollars.
What is Lock Rekeying?
Rekeying means changing the internal pins and springs inside your existing lock cylinder so that old keys no longer work. You keep the same physical locks but get new keys.
How it works:
- Locksmith removes the lock cylinder
- Takes out the old pins and springs
- Installs new pins in a different configuration
- Cuts new keys to match the new pin setup
- Reinstalls the cylinder
Result: Your locks look exactly the same, but old keys won’t work. Takes 10-15 minutes per lock.
What is Lock Replacement?
Lock replacement means removing the entire lock hardware and installing completely new locks.
When you replace:
- Remove old deadbolts, knobs, and strike plates
- Install entirely new lock hardware
- Receive new keys for the new locks
Result: Brand new lock hardware with fresh keys. Takes 20-30 minutes per lock.

Can You Rekey Locks Yourself?
Technically yes, but we don’t recommend it.
DIY rekeying requires:
- Rekeying kit ($15-$30)
- Understanding of pin tumbler mechanics
- Patience and steady hands
- Risk of making locks unusable
Rekey to Match: Best of Both Worlds
The most popular choice for Austin homeowners is “rekey to match” - where we rekey all your locks so one key opens everything.
Benefits:
- One key for front, back, and side doors
- No more fumbling with multiple keys
- Easy to make spare keys
- Same cost as regular rekeying
Perfect for:
- Front door, back door, garage entry
- Multi-story homes
- Families with kids (fewer keys to lose)
Smart Locks: A Third Option
Consider smart locks if:
- You want keyless entry
- Frequent Airbnb/rental use (temporary codes)
- Kids come home before you
- Integration with home automation
