FAQs: Everything You’ve Ever Wanted to Ask a Locksmith


When it comes to locks, keys, and security, people often have a lot of questions. At Keymex Locksmith in San Antonio, we’ve answered thousands of calls from homeowners, business owners, and drivers who all want the same thing: fast, reliable, and trustworthy locksmith service.
Here are answers to some of the most common questions we get – everything you’ve ever wanted to ask a locksmith.
1. What services does a locksmith provide?
Locksmiths do more than just unlock doors. At Keymex Locksmith, we handle:
- Residential lock installation, repair, and rekeying
- Automotive key replacement, programming, and lockouts
- Commercial master key systems and access control
- Emergency lockouts for home, business, and vehicles
- High-security lock upgrades and smart lock installation
2. Can a locksmith make a key without the original?
Yes! Professional locksmiths can cut and program keys even if you’ve lost the original. We use specialized tools to decode your lock or retrieve the key information from your car’s VIN number for automotive keys.


3. How much does a locksmith cost in San Antonio?
Costs vary depending on the service. A simple lock rekey may cost less than a full lock replacement, while high-security systems or car key programming may be higher. At Keymex Locksmith, we provide transparent pricing before any work begins – no hidden fees.
4. What’s the difference between rekeying and replacing a lock?
- Rekeying: We change the pins inside your lock so old keys no longer work. This is faster and less expensive.
- Replacing: We install an entirely new lock. This is recommended if your lock is damaged or outdated.
5. Can a locksmith program a car key fob?
Absolutely. Our locksmiths can program transponder keys, remote fobs, and push-to-start proximity keys for most makes and models – usually faster and cheaper than the dealership.
6. Are locksmiths available 24/7?
Many are, but not all. At Keymex Locksmith, we provide fast emergency locksmith services across San Antonio, day or night.
7. How do I know if a locksmith is legit?
Look for:
- A Texas Department of Public Safety license
- A physical business address in San Antonio
- Branded service vehicles and uniforms
- Transparent pricing with no bait-and-switch tactics


8. Can a locksmith open a safe?
Yes! Our technicians are trained to unlock, repair, or change safe combinations without damaging the contents inside.
9. Will a locksmith damage my locks when unlocking them?
No. Professional locksmiths have the right tools to unlock doors without causing damage. Drilling is always the last resort and only used if the lock is beyond repair.
10. Why should I hire a locksmith instead of a handyman?
Handymen may install basic locks, but locksmiths are licensed security professionals with the training to handle rekeying, high-security locks, key programming, and emergency lockouts.
