Consistent working frequency
The working frequency of the the selected wireless remote control shoule be the same as the original one. At present, the common remote control frequency on the market are 315MHZ/330MHZ/390MHZ/430MH/433MHZ (usually are 315MHZ and 433MHZ). The frequency of most remote controls can be distinguish by the face value on the crystal oscillator. 

Consistent coding chip 

Learning code    HS1527/EV 1527/HT6P20B, etc.
Fixed code         HS2260/HS2262/PT2264, etc.
Rolling code      HCS301/HCS300/HCS200, etc. (If it is HCS rolling code, the brand must be consistent)
The encoding chip of the remote control can be viewed by disassembling the PCB board of the remote control. 

Consistent oscillation resistance
When configuring the wireless remote control, the fixed code and the learning code oscillating resistance should be the same.
The resistance value of the oscillation resistance can be checked at the specified pin of the chip.
 

Consistent coding data 
The coded data of the wireless remote control should be the same. If it is a fixed code remote control, please weld the data pins accordingly. If it is a learning code remote control, you need to match code with a receiver with learning function.

If the original wireless remote control is a fixed code or a learning code.You feel that the pairing is still too complicated and  don’t understand the match method, you can contact our customer service to answer your questions. Of course, you can also choose the copy type wireless remote control.The copy type remote control is simple to operate, only need to copy with the original remote control.
