• What cities do you serve?

• Are you open 24 hours?
Our retail shop in Arroyo Grande is open:

Mobile locksmith service calls are available Monday–Friday from 9:00 AM–5:00 PM.
After-hours emergency locksmith service is also available Monday–Friday.
We are closed weekends.
• Are you a local locksmith or a dispatch service?
We are a locally owned locksmith business serving our community directly. When you call us, you are speaking with our team—not a national call center or third-party dispatch service.
• What does it mean to rekey a lock?
Rekeying means adjusting the internal pins inside your existing lock so that old keys no longer work. After rekeying, the lock will operate with a new key while keeping the same hardware installed on the door.
• Should I rekey my locks when I buy a new home?
Yes, rekeying is usually recommended when moving into a new home. Previous owners, contractors, neighbors, or service providers may still have copies of the original keys. Rekeying ensures that only your new keys will work.
• How much does it cost to rekey a lock?
The cost depends on the number of locks and the type of hardware involved. Because every situation is different, we typically provide pricing after learning a little more about the job. Feel free to call us for a quick estimate.
• Do you install access control systems?
Yes. We install and service many types of access control systems that allow businesses to control who can enter certain areas and when.
• Do you install or repair door closers?
Yes. Door closers are commonly used on commercial doors to ensure they close properly after being opened. We can install new closers, adjust existing ones, or repair closers that are slamming or not closing correctly.
• Can you help businesses manage keys for multiple employees?
We do this. Many businesses use master key systems, which allow certain keys to open multiple doors while other keys only open specific areas.
• Can you upgrade our doors to keyless entry?
Yes. Many businesses choose to upgrade to keypad or credential-based entry systems to eliminate the need for physical keys. These systems can make it easier to manage employee access and change permissions when needed.
• What is your cancellation policy?
We require at least 24 hours' notice to cancel or reschedule an appointment. Cancellations or changes made with less than 24 hours' notice are subject to a cancellation fee.
• Can you make multiple locks work with the same key?
In many cases, yes. If the locks are compatible, they can often be rekeyed so that one key works for several doors, making things more convenient.
• Do you install smart locks?
We do. We install many types of electronic and smart locks.
• What's it like to work with you?
Collaborative, honest, and straightforward. We're here to guide the process, bring ideas to the table, and keep things moving.
• Do you work with businesses and property managers?
Yes. We provide locksmith services for commercial properties, property managers, and businesses. This can include rekeying, hardware installation, and master key systems.
• Do you have a storefront or shop location?
Yes, we are located at 601 East Grand Avenue in Arroyo Grande.
• Are you licensed?
Yes, we have a locksmith license as well as a contractor's license.
• Do you install panic bars or exit devices?
Yes. We install and service panic hardware and exit devices commonly used on commercial buildings, schools, and other public spaces. These devices allow doors to open quickly from the inside during an emergency.
• Do you install ADA-compliant door hardware?
Yes. Many commercial buildings require door hardware that complies with accessibility standards, including properly functioning door closers, lever handles, and exit devices. We can help ensure hardware operates safely and meets accessibility requirements.
• Do you cut key blanks brought in by customers?
For quality and reliability, we only cut keys using blanks supplied by our shop. We do not cut customer-supplied key blanks.
• How many locksmiths do you have?
We are a small, family-owned and operated business with one locksmith and one person managing our retail shop and office. We're locals ourselves and are proud to be part of a business that has served the Central Coast since 1969. When you call or visit Frank's Lock & Key, you're working directly with our local team—not a call center.
