Each one is not as secure as the other, but have individual disadvantages and advantages.

Traditional Single-Key or Simple Key System

One key can open all the locks connected to the same pin tumbler lock cylinder in a traditional single key system. This type of master key is the least in terms of versatility. It can only open locks with the same pin arrangement as it has.

Multi-Key System

A multi-key system provides several different keys that can each open only certain locks within the building. A more sophisticated system with an arrangement that is pyramidal in nature. In a residential settings, a single key can open common areas like lobbies and public balconies.

Restricted Multi-Key/Great Grand Master Key System

The restricted multi-key system works by having a single key open or granting access to all the locks and areas in a building. Commonly called the great grand master key system, the arrangement involves lower-ranking keys that work for a particular lock or door only, while the great grand master key opens all the locks or doors in the building. Less security if in the wrong hands.

What Are Master Wafers?

Master wafers are small pieces of metal installed in the locks to prevent them from opening and allow minimal access. The wafers sit in between the gate and driver's pins: when there is no key inserted, they block the bottom of the cylinder; when a key is inserted, they raise out of their hole, allowing the cylinder to turn. They are an important part of the master key system as well-arranged master wafers will translate to better security and smooth operation.

As reiterated earlier, master key systems are security systems that allow the people who have access to keys to specific locks or rooms. This keying system is mostly made available to landlords and government officials. Making use of them for criminal intentions is highly discouraged. Instead, homeowners are advised to seek directives from the authorities.

How Master Key Systems Work

A master key system provides access by using one key to open multiple locks. Essentially, it is the responsibility of the building owner to select which areas should be accessible. Each key controls more than one lock. It works to allow or deny access to certain locks and doors. Oct 25, 2021

Most master key systems are arranged in a family-tree-like way, with the Great Grand Master or GGM being at the top of the rank. The GGM, as confirmed by skilled locksmiths from Fast Austin Locksmith, has unrivaled access to all the locks below it.

In comparison, other types of master key systems can only open a few or one lock. Little wonder why it should and can only be possessed by established organizations.

  • Traditional single-key

Car Key Replacement in Austin, TX

Losing every copy of a car key is one of those situations that goes from inconvenient to expensive fast — especially if you call the dealership first. Fast Austin Locksmith cuts and programs replacement car keys, transponder keys, and proximity fobs on-site in Austin for a fraction of dealer pricing, and we usually finish the job the same day you call.

Modern vehicles use immobilizer systems that require the new key to be programmed to the car's onboard computer. That is the part most generic locksmiths cannot handle. We invest in the diagnostic tools and software updates needed to program keys for nearly every make and model on the road in Austin, including push-to-start vehicles, smart fobs, sidewinder/laser-cut keys, and older transponder chips.

What We Bring to Your Location

  • Key-cutting machines for traditional, high-security, and laser-cut blanks.
  • OEM and high-quality aftermarket transponder keys and remote fobs for most Austin vehicles.
  • Programming tools for Ford, GM, Chrysler/Dodge/Jeep/RAM, Toyota, Honda, Nissan, Hyundai, Kia, VW, Audi, BMW, and more.
  • The ability to make a working key even when no original key is available.

Why It Pays to Call a Locksmith Before the Dealer

Dealerships in Austin often quote three to five hundred dollars for a single replacement smart fob and ask you to tow the vehicle in. We come to you — in a driveway, at work, at the grocery store — typically charge significantly less, and finish in 30 to 60 minutes for most vehicles. We will also cut and program a spare while we are already there, which is the smartest time to do it.
