Operating at 315 MHz, the Aftermarket Remote Key Fob (FCC ID AB01502T) serves as a direct replacement remote for a wide range of General Motors vehicles produced from the early 1990s through the mid-2000s. This unit is identifiable by its FCC registration under AB01502T and transmits on the standard 315 MHz frequency used across GM’s keyless entry platform during that era. The Aftermarket Remote Key Fob (FCC ID AB01502T) covers Chevrolet, GMC, and Cadillac models — spanning trucks, SUVs, sedans, and vans. Compatible vehicles all share GM’s legacy remote receiver architecture, and a correctly programmed fob will lock, unlock, and in some configurations activate panic or hatch-release functions depending on the specific vehicle.

Vehicle Compatibility for the Aftermarket Remote Key Fob (FCC ID AB01502T)

One of the distinguishing traits of this remote is its broad fitment list across the GM family. The following vehicles have been validated as compatible:

• Cadillac Escalade (1999–2000)
• Chevrolet Astro (1995–2005)
• Chevrolet Blazer (1995–2005)
• Chevrolet Camaro (1993–2002)
• Chevrolet Cavalier (1995–2005)
• Chevrolet Express (1996–2002)
• Chevrolet Malibu (1997–2003)
• Chevrolet Monte Carlo (1995–1999)
• Chevrolet S-10 (1994–2004)
• Chevrolet Silverado (1999–2007)
• Chevrolet Suburban (1992–1999)
• Chevrolet Tahoe (2000–2006)
• GMC Jimmy (1995–2005)
• GMC Safari (1995–2005)
• GMC Savana (1996–2002)

This fitment range reflects the fact that GM used a shared keyless entry receiver module across many of its truck-based and car-based platforms during this production window. The same 315 MHz signal protocol was standardized, meaning a single aftermarket remote design can serve all of these applications as long as the FCC ID and frequency match.

315 MHz Frequency and GM Remote Architecture

The 315 MHz operating frequency was the dominant standard for North American GM keyless entry systems throughout the 1990s and into the 2000s. This frequency band is regulated by the FCC for low-power unlicensed transmitters, and the AB01502T registration confirms compliance with Part 15 rules governing such devices. The remote communicates with a receiver module typically mounted behind the instrument panel or integrated into the body control module (BCM), depending on the model year and platform.

GM’s remote protocol during this era used a rolling-code system to prevent replay attacks. Each button press transmits a unique encrypted code that the vehicle’s receiver validates against its stored code sequence. This means the fob must be properly programmed — or “learned” — to the vehicle before it will function. An unprogrammed unit will transmit on the correct frequency but the vehicle will reject the code.

Programming Procedures

Most GM vehicles from this generation support an on-board programming sequence that does not require specialized diagnostic equipment. The general procedure for many of these models involves the following steps:

1. Enter the vehicle and close all doors.
2. Insert the ignition key and cycle it to the “ON” position without starting the engine, then back to “OFF.” Repeat this sequence a specific number of times (commonly two or three cycles, depending on the model) within a defined time window.
3. Listen for the door locks to cycle — this audible confirmation indicates the vehicle has entered programming mode.
4. Press and hold the lock and unlock buttons on the remote simultaneously for approximately 15 seconds, or until the door locks cycle again to confirm enrollment.
5. If programming additional remotes, repeat step 4 for each unit before exiting programming mode.
6. Turn the ignition to “ON” to exit programming mode.

The exact number of ignition cycles and button-hold durations can vary between platforms. Chevrolet Silverado and Tahoe models from 1999 onward, for example, may require a slightly different sequence than a 1995 Blazer. Automotive locksmiths familiar with GM systems will recognize these variations and can confirm the correct procedure for the target vehicle. For vehicle owners attempting self-programming, consulting the owner’s manual for the specific model year is strongly recommended before beginning.

Some later models in this fitment list — particularly the 2003–2007 Silverado and 2004–2006 Tahoe — may require a diagnostic tool such as a Tech 2 or equivalent aftermarket scan tool to program the remote if the on-board procedure fails or if all previously programmed remotes have been lost.

Aftermarket vs. OEM Considerations

This fob is an aftermarket replacement, meaning it is manufactured by a third party rather than General Motors. Aftermarket remotes registered under FCC ID AB01502T are designed to replicate the signal characteristics and form factor of the original OEM units. For vehicle owners, the primary advantage of an aftermarket unit is cost — these remotes typically sell for a fraction of the dealership price for an OEM-branded fob.

From a functional standpoint, a properly manufactured aftermarket remote operating at 315 MHz with the correct rolling-code protocol will perform identically to the factory original once programmed. Locksmiths regularly stock and program aftermarket remotes for GM vehicles in this era, and the programming procedure is the same regardless of whether the fob carries an OEM or aftermarket brand label.

One consideration when selecting an aftermarket remote: confirm the FCC ID printed on the unit matches AB01502T. Generic remotes with different FCC IDs may operate at 315 MHz but use incompatible code protocols, resulting in a unit that cannot be learned by the vehicle. The FCC ID is the most reliable identifier for ensuring protocol compatibility.

When to Contact a Locksmith

Vehicle owners who are not comfortable with the on-board programming sequence, or who have lost all functioning remotes, should contact an automotive locksmith. A locksmith equipped with GM-compatible diagnostic tools can program the remote quickly and verify its function on-site. This is particularly relevant for the later model years in the fitment list where scan-tool programming may be required.

For locksmiths servicing fleets or customers with multiple GM vehicles from the 1990s and 2000s, stocking the Aftermarket Remote Key Fob (FCC ID AB01502T) is efficient given its broad cross-platform coverage. A single SKU addresses fifteen distinct vehicle applications, reducing inventory complexity while covering a significant portion of the GM service population still on the road.
