Frequently Asked Questions
At AA Key and Lock Services, we know security questions come up often—especially when it comes to protecting your home, business, or vehicle.
To help you make informed decisions, we’ve answered some of the most common questions our customers ask about locksmith services, security upgrades, and emergency assistance.
Re-keying vs. Changing Locks: Which is better?
Re-keying changes the internal mechanism of your existing lock so it works with a new key, without replacing the entire lock. This is a cost-effective way to boost security after moving, losing keys, or during employee turnover. Changing locks is ideal if the hardware is damaged or outdated. Our team can help you decide which option is best for your situation.
Do you offer key-cutting services?
Yes. We provide precise key cutting for residential, commercial, and automotive needs. We can cut keys from codes, locks, or existing keys, and we stock a wide variety of key blanks to fit most applications.
Do you offer lock repair?
Yes. We repair and replace damaged locks, cylinders, and key mechanisms to restore proper security. Whether for homes, businesses, or vehicles, our technicians provide reliable lock repair solutions.
What are your payment options?
We accept cash, credit cards, debit cards, and business checks (for commercial clients). Our goal is to make payments simple, secure, and convenient for all of our customers.
Should I change my locks after a move?
Yes. It’s strongly recommended to re-key or replace all locks after moving into a new home, since you can’t know who may still have copies of the old keys. We offer fast, professional re-keying and replacement services to ensure your new property is fully secure.
Do you install deadbolts?
Yes. We can install new deadbolts on most doors by drilling and aligning the hardware to reinforce your entry points. Deadbolts are one of the simplest and most effective ways to improve home or business security.
