Fully pre-installed with a 46 anti-theft chip, 315MHz RF module, and CR2016 battery, this 315MHz car remote key with 46 chip requires no additional component sourcing. Locksmiths can complete vehicle pairing directly, shortening per-customer service time and boosting operational efficiency, especially for bulk key replacement projects.
The 3+1 button layout fully replicates the original key’s core functions, including Lock, Unlock, Hatch Release, and Panic Alarm. End users face no learning curve for operation, minimizing customer complaints and return rates for your business.
We offer stable, large-volume supply capacity with flexible minimum order quantities (MOQs), catering to both small-batch orders for independent locksmiths and bulk wholesale for regional distributors. Compared to original OEM parts, this key delivers significant cost savings, expanding your profit margins and market competitiveness.
This remote key operates via two core systems: RF remote control and immobilizer authentication. When a user presses a button, the 315MHz RF module transmits an encrypted wireless signal to the vehicle’s Body Control Module (BCM), which verifies the signal’s legitimacy and executes the corresponding lock/unlock/hatch command. Meanwhile, the built-in 46 transponder chip performs two-way encrypted authentication with the vehicle’s Engine Control Unit (ECU) via electromagnetic induction when the key is inserted into the ignition. The engine will only start if the chip’s unique ID code matches the vehicle’s pre-stored data, delivering the same anti-theft protection as the original key.
Pre-purchase verification: Confirm the original key’s FCC ID, button layout, frequency, and chip type match this 3+1 Buttons KR55WK45144 remote key to avoid incompatibility.
Professional programming required: This key must be paired by a certified automotive locksmith with dedicated key programming equipment; self-programming is not supported for this vehicle model.
