How is mobile dispatch handled?
Our mobile dispatch system is built to serve you. In most service areas, technicians are dispatched to your location so you have help when you need vehicle lockout services or home entry.
Is it better to rekey a lock or completely replace it?
If your hardware is in good mechanical condition but you want to restrict access, such as moving into a new home, lock rekeying services are a cost-effective choice. If the lock is damaged or you want to upgrade your security grading, full lock installation is the better route.
Can you create a new car key without the original?
Yes. Our technicians can cut and program a new key from scratch using your vehicle's VIN and our diagnostic equipment. We offer car key replacement services for nearly all modern automotive brands.
What is a master key system and how does it benefit my business?
A master key system lets managers open all doors with one key while restricting employees to specific areas with their own. It is a core part of our commercial locksmith solutions.
Do you install smart locks and electronic deadbolts?
Yes. We stay current with home automation trends and provide smart lock installation services, integrating keyless entry into residential or commercial properties.
Are your technicians licensed and insured?
Yes. Every technician at Locksmith Guarantee is licensed, bonded, and insured, with background checks and ongoing training.
Can you repair a lock instead of replacing it?
Often a malfunctioning lock just needs lubrication, realignment, or a minor part replacement. We will always attempt a cost-saving lock repair before recommending a full replacement.
Do you offer commercial access control systems?
Yes, we design and install electronic access control systems, including key fob readers, biometric scanners, and digital keypads, so you can monitor and restrict entry to sensitive areas.
