Expert Lock Installation for Homes and Residential Complexes
Access cards and key fobs are essential for operating modern commercial entry systems. Having additional credentials ready helps keep operations running smoothly and avoids unnecessary disruptions. Professional key card duplication ensures your team has the access they need without compromising security.At 247 Mobile Locksmith, we provide reliable key card and key fob duplication services for businesses throughout your area. Our technicians can often complete the duplication process on site during a single visit, saving you time and coordination headaches. We work carefully to ensure new credentials function exactly like the original. Clear communication and efficient service are always part of the process.
We work with many common commercial card and fob formats used in offices, apartment buildings, and parking facilities. This includes widely used proximity systems as well as higher security credential types, depending on configuration. Our technicians carry professional equipment that allows them to read existing credentials and write matching data to new cards or fobs. Each duplication is handled with attention to accuracy and compatibility.
The process itself is straightforward. You provide a working card or fob as a reference, and we duplicate the encoded data onto new credentials. In some high security systems, duplication may require administrator level access or may not be permitted at all. When that happens, we explain your options clearly so you can decide the best path forward for your system. Our service is available 7 days a week and can often be combined with other commercial locksmith work you may need.
If your business needs dependable key card or key fob duplication near you, 247 Mobile Locksmith is ready to help. Contact us today to keep access simple, secure, and fully under your control.

Questions people ask
Do you provide the locks, or do I need to buy them?
We carry a complete selection of residential locks in our service vehicles, so we can typically provide everything needed to complete your installation in one visit. However, if you have already purchased hardware or have a specific product in mind, we are happy to install locks you provide.
Can you upgrade my home to high security locks?
Absolutely. We can replace standard locks with Grade 1 high security deadbolts that provide significantly better protection against picking, bumping, and drilling. These locks feature hardened steel components and complex pin configurations that make them much harder to defeat than basic hardware store options.
How long does lock installation take?
The exact time depends on whether we are fitting into existing door prep or need to drill new holes, and whether any modifications are needed to your door or frame for proper alignment.
