JLR OEM Key Types

OEM Keys (HW15-16, HW19-26): Original Equipment Manufacturer keys made by or for JLR. These are the genuine keys with full factory quality and features.

Non-OEM Keys (HW17, HW18): High-quality aftermarket alternatives that are fully compatible with LOCK50 tools. They offer excellent value and support keyless entry functionality.

Both types work reliably with LOCK50 programming tools, but OEM keys are recommended for customers who want original manufacturer quality.

UWB (Ultra-Wideband) is an advanced wireless technology that provides precise location detection and enhanced security for keyless entry systems.

Benefits of UWB Keys (HW21-HW26):

• True hands-free keyless entry when approaching the vehicle
• Enhanced security against relay attacks
• More accurate proximity detection
• Works on newer JLR vehicles with UWB-compatible RFA modules

UWB keys can also function as Non-UWB keys on older vehicles without UWB support.

The frequency depends on your vehicle's region:

Always match the key frequency to your vehicle's original specification to ensure proper communication.

Keyless entry support depends on both the key type AND your vehicle's RFA module:

Match the key to your specific vehicle brand for proper physical and electronic compatibility.

NCF29A1 is the transponder chip used in all LOCK50-supported JLR keys. It's manufactured by NXP Semiconductors and is the standard chip for modern JLR vehicles.

Key features of NCF29A1:

• Advanced cryptographic security
• HITAG AES encryption support
• Compatible with JLR's security protocols
• Used across all HW15-HW26 key variants

The RFA (Remote Function Actuator) part number determines your vehicle's key compatibility. You can find it by:

• Using the LOCK50 diagnostic tool to read RFA information
• Checking the RFA module label in your vehicle
• Looking up your VIN with JLR Topix or SDD
