T131 Lotus Key and RF Receiving Module

Product name: LOTUS EMIRA Key Fob
Model No.: T131

Key product introduction

1. Function is introduced
The key has three keys, each representing a different function.

  1. Unlock: Press the key to unlock for 0.5s, and the key sends out high frequency signal to unlock
  2. Locking: press the key locking for 0.5s, and the key sends out high frequency locking signal
  3. Trunk opening or closing: Long press the trunk for about 5s, and the key will send the trunk high frequency signal
  4. PEPS:When the car key is near the sensing area, as long as the door handle is touched, the key receives the low-frequency signal of the door handle and passes certification, the key sends a high-frequency signal of passive entry, and the vehicle is unlocked. When the key is placed in the car, it will drive the lowfrequency antenna to find the key, and the key will reply to the corresponding high-frequency signal after the low-frequency certification, and the vehicle will start.
