Our Subaru smart keys are divided into 4D chip and 8A chip. The main models are HYQ14AHC and HYQ14AHK, which are divided into 315MHz and 433MHz. In addition to smart remote keys, we also have Subaru's Transponder keys. The Subaru Smart Key enables keyless entry, making it easy to enter the vehicle without actually inserting the key. The user only needs to approach the vehicle and the door will automatically unlock if the key is within a certain range. Additionally, the key supports push-button start systems, eliminating the need for traditional key insertion.
