Fitments for the Bosma Remote Key Fob (FCC ID OUC60270) span a wide range of General Motors vehicles from model years 2000 through 2018, including the Buick Enclave, Buick Lucerne, Cadillac DTS, Cadillac Escalade, Cadillac SRX, and numerous Chevrolet platforms such as the Silverado, Tahoe, Suburban, and Traverse. Across these vehicles, the unit handles keyless entry functions over a 315 MHz radio frequency link between the remote and the vehicle’s body control module (BCM). Each Bosma Remote Key Fob (FCC ID OUC60270) communicates with the BCM during a coded RF handshake that authenticates the device before unlocking or locking the doors. Owners replacing the fob should expect a programming procedure that pairs the device to the specific vehicle, typically performed through an on-board learn sequence or with a professional diagnostic tool. When ordering a Bosma Remote Key Fob (FCC ID OUC60270), confirm compatibility with the exact model year and trim level, as sub-model variations within a generation can occasionally affect remote compatibility.

Bosma Remote Key Fob (FCC ID OUC60270) – Vehicle Compatibility

The FCC ID OUC60270 is one of the most widely used remote identifiers in the GM ecosystem. Bosma Enterprises produces this aftermarket version to serve as a direct replacement for the factory-issued remote. Below is the validated list of vehicles that accept this device:

• Buick Enclave – 2008 through 2017
• Buick Lucerne – 2006 through 2011
• Cadillac DTS – 2006 through 2011
• Cadillac Escalade – 2007 through 2014
• Cadillac SRX – 2004 through 2009
• Chevrolet Avalanche – 2007 through 2013
• Chevrolet Captiva – 2006 through 2018
• Chevrolet Equinox – 2005 through 2009
• Chevrolet Express – 2008
• Chevrolet Impala – 2006 through 2013
• Chevrolet Monte Carlo – 2000 through 2007
• Chevrolet Silverado – 2007 through 2013
• Chevrolet Suburban – 2007 through 2014
• Chevrolet Tahoe – 2007 through 2014
• Chevrolet Traverse – 2009 through 2017

This remote is strictly a keyless entry device — it transmits lock, unlock, and panic signals at 315 MHz. It should not be confused with a transponder key or smart proximity fob. A separate mechanical or transponder key is still required for ignition on every vehicle listed above.

How the OUC60270 Remote Functions

All of the GM vehicles on this fitment list use a body control module to manage keyless entry. When a button is pressed on the fob, a coded RF signal at 315 MHz is transmitted to the vehicle’s BCM antenna. The BCM validates the rolling code embedded in the signal and, if authenticated, executes the requested function — whether that is unlocking the driver door, unlocking all doors, locking, or triggering the panic alarm. The rolling code protocol means the transmitted value changes after every press, preventing replay attacks where an intercepted signal could be reused by a third party.

Because the remote relies on rolling codes, any replacement unit must be programmed to the target vehicle’s BCM before it will function. An unprogrammed device, even if it matches the correct FCC ID, will not communicate successfully with the vehicle.

Programming Procedures for GM Keyless Entry Remotes

Many of the GM vehicles compatible with this remote support an on-board programming method that does not require specialized equipment. The general on-board procedure for GM vehicles of this era follows a pattern:

1. Enter the vehicle, close all doors, and insert the ignition key to the ON position without starting the engine.
2. Within a specific time window, press and hold the door lock switch (typically on the driver door panel) in the unlock position.
3. While holding the unlock switch, press and release the lock switch a set number of times. The exact count varies by model and year — consult the vehicle’s service manual for the precise sequence.
4. Release both switches. The door locks will cycle (lock and unlock) to indicate the BCM has entered learn mode.
5. Within 30 seconds, press and hold both the lock and unlock buttons on the new remote simultaneously until the door locks cycle again, confirming successful pairing.
6. Repeat step 5 for any additional remotes that need to be programmed during the same session.
7. Turn the ignition to OFF to exit learn mode.

Some vehicles on this list — particularly later model years of the Cadillac Escalade, Chevrolet Traverse, and Buick Enclave — may require a diagnostic scan tool to enter programming mode. Automotive locksmiths and dealership service departments carry tools capable of initiating the BCM learn sequence on these platforms. If the on-board method fails or is not supported, professional programming through a scan tool is the recommended path.

OEM vs. Aftermarket Considerations

The Bosma version of the OUC60270 remote is an aftermarket product designed to replicate the function and form factor of the original GM remote. Aftermarket remotes for GM vehicles in this era have a strong track record of reliability because the underlying rolling code protocol is well-established and the 315 MHz hardware is straightforward. The primary advantages of choosing an aftermarket unit from Bosma Enterprises include lower cost compared to dealer-sourced OEM remotes and broad availability.

One point to verify before purchasing: the button layout on OUC60270-designated remotes can vary depending on the specific vehicle application. Some versions include a remote start button, while others carry only lock, unlock, and panic. The correct button configuration depends on whether the vehicle was factory-equipped with remote start capability. A mismatch in button count will not prevent the remote from programming, but the extra button simply will not function on a vehicle that lacks the corresponding module.

Battery and Maintenance

This remote uses a standard CR2032 coin cell battery, which is the most common battery type for GM keyless entry remotes of this generation. Expected battery life ranges from two to four years depending on usage frequency. Signs of a weakening battery include reduced operating range and intermittent response from the vehicle. Replacing the battery does not require reprogramming — the rolling code memory is retained through a battery swap as long as the internal circuitry maintains power during the exchange. To swap the battery, the remote case is typically separated along a seam using a flat-blade screwdriver or coin, the old cell is removed, and the replacement is inserted with the correct polarity orientation.

When to Contact a Locksmith

While the on-board programming procedure for this remote is accessible to many vehicle owners, several scenarios call for professional assistance. If the vehicle’s BCM does not enter learn mode using the standard switch sequence, a locksmith with GM-compatible diagnostic software can force the module into programming state. Vehicles that have had a BCM replacement or a major electrical repair may also need scan-tool-level access to re-register all remotes. Additionally, automotive locksmiths can verify that the replacement remote’s FCC ID and frequency match the vehicle’s receiver specifications before programming — an important step that eliminates guesswork when dealing with vehicles that spanned multiple remote designs across a single generation.
