KEYDIY Universal Smart Remote Key Amber Yellow 4 Button for 46 47 48 49 4A MQB48 5C Chip ZB71-4

The KEYDIY ZB71-4 is a universal smart proximity remote from KEYDIY's ZB Series, featuring a 4-button layout in a distinctive Amber Yellow premium smart key housing. Designed for push-to-start / keyless-go vehicles, it provides hands-free passive entry and proximity ignition functionality. The modern supercar-inspired design gives the remote a premium appearance — but functionally, this remote is universal and not tied to any specific make.

ZB Series smart keys are designed specifically for vehicles equipped with push-to-start ignition systems. The ZB71-4 supports applications using 46, 47, 48, 49, 4A, MQB48, and 5C chip types, allowing a single universal smart remote to cover a wide range of vehicle applications. This dramatically reduces the number of individual OEM-style smart keys locksmiths and dealers need to keep in inventory. Button functions and configurations can also be generated and modified through compatible KEYDIY tools to match the target vehicle.

Programming requires the KEYDIY KD-MAX or KD-X2. The ZB Series is multi-frequency and can be configured to match the target smart key during generation and programming. KEYDIY's vehicle database is updated regularly to expand compatibility as additional push-to-start vehicle applications become available.

The ZB71-4 features a replaceable emergency blade design, allowing the appropriate blade type to be selected according to the target vehicle.
