Due to some customers gave feedback that Xhorse Remote Tester cannot detect IR key normally, eobdtool.co.uk engineer specially tested this device on 315 (300 Mhz- 320Mhz)/433/433 IR (Benz 433 key IR) keys respectively. Finally, the results proved that the device worked well, the actual reason is that the IR signal of the key to open the trunk is weak. The best way to test the device is to press all key buttons once.
