Why Mercerville Chooses Us
Car Key Duplication
Spare car keys — including transponder and chip keys — cut and programmed.
Tested Copies
Every copy is checked so it turns smoothly the first time.
House & Office Keys
Standard home and business keys copied accurately, often while you wait in Mercerville.
Mailbox & Padlocks
Small keys too — mailboxes, padlocks, cabinets, and more.
When to Make a Spare
The best time to copy a key is before you lose it. New home, new tenant, new employee, or simply a backup left with someone you trust — a spare in hand saves an expensive lockout call later.
Why Not Just Use a Kiosk?
Hardware-store machines handle basic keys, but they often produce slightly-off copies and can't touch transponder, high-security, or restricted keys. A Mercerville locksmith cuts to spec and can duplicate the keys those kiosks reject.
Keys We Cut & Duplicate
In Mercerville the common requests are house and apartment keys, office and commercial keys, mailbox and padlock keys, and car keys (including chip/transponder keys and remote fobs). If it opens a lock, it can usually be copied.

Frequently Asked Questions
Will the copy work as well as the original?▾
A properly cut and tested duplicate works just like the original. Worn originals are best copied before they start to fail.
Can high-security or "do not duplicate" keys be copied?▾
Often yes, with the right authorization. Local locksmiths can cut many restricted and high-security keys that hardware-store kiosks cannot.
Can you make a key with no original?▾
Yes. A locksmith can often cut a working key from the lock itself or by code, even if you have no original to copy.
Do you cut keys on-site in Mercerville?▾
Mobile locksmiths in Mercerville can cut most keys right at your home or business.
