Q01 How is mobile locksmith dispatch handled in Maryland?
Our mobile dispatch system coordinates directly with technicians positioned across Central Maryland, including Montgomery County, Prince George's County, Anne Arundel County, Howard County, and Baltimore. When you contact us with your address and service requirement, our nearest mobile technician is dispatched in a fully equipped vehicle carrying computer key cutters, locksets, and diagnostic tools to resolve your issue on-site.
Q02 Is it better to rekey a lock or completely replace it?
If your existing locksets are in good mechanical condition and you simply want to invalidate old keys (for example, when moving into a new home or after staff turnover), lock rekeying is significantly more cost-effective. We adjust the internal pins to match new keys while preserving your hardware. Full lock replacement is recommended when hardware is physically damaged, worn out, or when upgrading to high-security or smart digital keypads.
Q03 Can you make a replacement car key without having the original?
Yes. Using your vehicle's Vehicle Identification Number (VIN) and proof of ownership, our mobile automotive locksmiths can generate a factory-spec key from code. We cut high-security laser sidewinder blades and connect specialized diagnostic software to your vehicle's OBD port to pair transponder chips and push-to-start smart fobs directly at your vehicle's location.
Q04 What is a master key system and how does it benefit a business?
A master key system allows business owners or property managers to open every door within a facility using a single master key, while assigning individual keys to employees that only operate designated doors. This streamlines commercial access, enhances security, and eliminates the hassle of carrying heavy key rings. It is a cornerstone of our commercial locksmith solutions.
Q05 Do you install smart locks and keyless deadbolts?
Yes. We install and configure a wide variety of keyless deadbolts, touchscreen electronic locks, and biometric fingerprint scanners from trusted brands. Whether you need a standalone keypad for your home or an app-connected system that integrates with your smart home ecosystem, our technicians ensure proper door alignment and smooth motorized latch operation.
Q06 Are your locksmith technicians licensed, bonded, and insured?
Yes. Locksmith Guarantee MD is fully licensed and bonded under Maryland License #507, maintaining comprehensive liability insurance. Every technician undergoes background checks and technical training to ensure professional workmanship and respectful conduct on your property.
Q07 Can you repair a sticking lock instead of replacing it?
In many instances, yes. Often a malfunctioning lock is suffering from dry or clogged internal pins, door sag, or misaligned strike plates. We always inspect the mechanism first and attempt a cost-effective lock repair, adjustment, and precision lubrication before recommending full replacement.
Q08 Do you design and install commercial access control systems?
Yes. We install electronic access control solutions including key fob proximity readers, electric strikes, digital keypads, and magnetic locks for commercial buildings, warehouses, and corporate offices. These systems allow management to revoke credentials professionally and maintain strict audit trails of entry activity.
