1. Our smart car keys are brand new and have not been used, so before using them, you need to go to a professional for programming.
2. Compared with ASK, FSK is more resistant to nonlinearity, fast fading, and adjacent channel interference, and can work in a small SNR environment due to the effect of exchanging SNR for bandwidth.
3. The smart key and remote are in optimal working condition. If the car remote keys have any questions, please consult our staff in time.
4. To emergency unlock/lock the car door, after unlocking through the lock cylinder and opening the driver's door, you must press the unlock button on the car key or turn on the ignition switch, otherwise an alarm will be triggered.

Our 13510245 Cadillac remote key is manufactured to replicate the original key’s protocol and fitment, ensuring 100% compatibility with target models’ body control module (BCM) and anti-theft system. This eliminates rework and returns, while delivering identical functionality to the factory key.
Adopting FSK modulation technology, this aftermarket Cadillac smart key offers exceptional resistance to non-linear distortion, fast fading, and adjacent channel interference, maintaining stable transmission even in low SNR environments, reducing customer complaints and service callbacks.
Equipped with a premium NCF2951E chip with HITAG 2 46 encryption, the key meets original vehicle security standards, preventing unauthorized cloning. Each unit undergoes full functional testing before shipment, supporting your business’s reputation for quality service.
This HYQ2EB 433MHz Smart Key for Cadillac XTS delivers OEM-level performance at a fraction of the OEM cost, creating higher profit margins for your business, with flexible bulk ordering options to fit your inventory needs.
This 4+1Buttons HYQ2EB smart key operates via two-way wireless communication between the key’s built-in chip and the vehicle’s BCM and immobilizer system. At 433MHz frequency, the key sends encrypted RF signals via FSK modulation when a button is pressed; the vehicle’s receiver validates the encrypted ID through the 1551A-2EB IC, then executes the corresponding command. For passive entry, the key automatically responds to the vehicle’s low-frequency wake-up signal, completing identity verification without manual operation. The integrated HU100 mechanical key blade serves as an emergency backup for manual door access if the battery is depleted, with built-in safeguards to prevent false alarms.
This key requires programming by a certified automotive locksmith or qualified technician via professional diagnostic equipment prior to use; end-user self-programming is not supported. Before programming, verify the vehicle’s FCC ID, part number, and chip type match the key’s specifications to avoid compatibility issues. For emergency door access, after opening the driver’s door via the lock cylinder, press the unlock button or turn on the ignition switch immediately to prevent triggering the anti-theft alarm. Instruct end-users to replace the CR2032 battery promptly when signal strength weakens. For bulk orders, we recommend pre-testing 1-2 units to confirm compatibility with your local programming tools.
A1: It is compatible with models matching FCC ID HYQ2EB and part numbers 13598516 / 13510245. Please confirm the original key’s specifications before ordering.
