VW Group OEM 5-Button Remote Head Key – KR5FS14-T | 315 MHz

Operating at 315 MHz with a 5C transponder chip, the VW Group OEM 5-Button Remote Head Key is a factory-specification remote head key designed for select Volkswagen vehicles produced from 2019 onward. This unit is identifiable by its five-button layout and the HU162 blade profile machined into the key’s metal insert. Inside the fob sits the 5C transponder responsible for immobilizer pairing with the vehicle’s engine control module. Compatible vehicles — including the Atlas, Jetta, and Tiguan — share the same electronic architecture that accepts this remote’s rolling-code signal. A correctly enrolled VW Group OEM 5-Button Remote Head Key will start the engine upon insertion and turning, while the integrated remote buttons handle lock, unlock, panic, trunk release, and remote-start functions from a distance. The device carries FCC ID KR5FS14-T, confirming its authorization for operation on the 315 MHz band within United States regulatory limits.

VW Group OEM 5-Button Remote Head Key — Technical Specifications

The key’s five physical buttons distinguish it from earlier four-button Volkswagen remotes. This additional button typically corresponds to a remote-start function, a feature that became standard across several Volkswagen models during the 2019 model-year refresh. The HU162 keyway — a high-security sidewinder profile — requires either a precision code-cut from bitting data or a skilled manual impression. Because HU162 blanks feature internal milling rather than conventional edge cuts, only equipment calibrated for this profile can produce an accurate duplicate.

The 5C transponder chip embedded in the key head communicates with the vehicle’s immobilizer through a challenge-response protocol. When the key is inserted into the ignition barrel, the immobilizer antenna ring energizes the transponder. The 5C chip then transmits its encrypted response. If the vehicle’s body control module validates the response, the engine is permitted to crank. Without a properly registered transponder, the starter motor may engage but the fuel and ignition systems will remain locked out.

Radio-frequency communication for the remote-control functions operates at 315 MHz, as documented under FCC ID KR5FS14-T. This frequency is standard for North American–market Volkswagen remotes of this generation. The rolling-code encryption protocol ensures that each button press transmits a unique signal, preventing simple replay attacks.

Vehicle Fitment and Year Coverage

Based on validated fitment data, the VW Group OEM 5-Button Remote Head Key is compatible with the following Volkswagen models and year ranges:

• Volkswagen Atlas — 2019 through 2024
• Volkswagen Jetta — 2019 through 2026
• Volkswagen Tiguan — 2019 through 2024

All three models transitioned to the MQB platform architecture during this production window, which standardized the immobilizer hardware and remote-control electronics across the lineup. This shared platform is why a single key SKU can serve multiple body styles — the underlying security module, antenna ring, and key cylinder accept the same transponder and blade profile regardless of whether the vehicle is a midsize SUV, a compact crossover, or a sedan.

Locksmiths should verify the vehicle’s specific model year and trim before ordering, as certain base-trim configurations in early 2019 production may have shipped with four-button remotes instead of five. Confirming the button count against the customer’s existing key or the vehicle’s option sticker prevents sourcing errors.

Programming Procedure Considerations

Registering a new remote head key to these Volkswagen models requires an advanced diagnostic tool capable of communicating with the MQB-generation immobilizer system. The process involves two distinct steps: transponder enrollment (so the 5C chip is recognized by the immobilizer) and remote pairing (so the 315 MHz remote functions are linked to the body control module).

Transponder enrollment on MQB-platform vehicles typically requires online authentication through the manufacturer’s security gateway. The diagnostic tool must establish a live internet connection to Volkswagen’s server, submit a token request, and receive an authorization code before the new transponder can be written into the immobilizer’s memory. This server-based security step was introduced to prevent unauthorized key additions and means that programming cannot be completed in areas without cellular or Wi-Fi connectivity.

Once the transponder is enrolled, remote pairing is handled through the same diagnostic session. The body control module is instructed to enter learn mode, at which point pressing a button on the new remote binds the 315 MHz signal to the vehicle. Most Volkswagen models in this generation support up to four paired remotes simultaneously. If a customer has lost all existing keys, the all-keys-lost procedure adds an additional security verification layer that may require proof of ownership documentation depending on the diagnostic platform being used.

Blade cutting should be performed before programming begins. The HU162 profile requires a dedicated clamp and cutter on an automated key machine. Manual decode from the existing lock cylinder is possible but time-intensive due to the internal-milling geometry. When bitting data is available from the dealer or an aftermarket code-retrieval tool, direct code-cutting is faster and more reliable.

OEM vs. Aftermarket Considerations

Because this is a factory-original Volkswagen part, the VW Group OEM 5-Button Remote Head Key offers guaranteed compatibility with the vehicles listed above. OEM units ship with the correct 5C transponder pre-installed, eliminating the need to source and solder a separate chip. The HU162 blade blank is factory-hardened and precision-ground, which contributes to smoother cylinder operation and longer wear life compared to some aftermarket alternatives.

Aftermarket remote head keys for these Volkswagen models do exist and may offer a lower price point. However, locksmiths should verify that any aftermarket unit uses an authentic 5C transponder and transmits on 315 MHz with the correct rolling-code algorithm. Incompatible transponder types will fail the immobilizer enrollment step entirely, and frequency mismatches will prevent remote-lock functionality even if the transponder programs successfully.

For vehicle owners, the decision often comes down to cost tolerance and urgency. OEM keys sourced through a locksmith or dealer carry a higher material cost but eliminate compatibility risk. A qualified automotive locksmith can cut and program this key on-site, often completing the entire process in under an hour — a meaningful advantage over dealer-only service, which may involve towing the vehicle and waiting for parts to arrive.
