Many factors may affect the operating range of the transmitter.  Some of these are: 

•  The condition of the battery in the transmitter. 

•  The operating environment (for example: downtown radio-frequency noise, airports, cellular 

phone towers…). 

•  Metal: any type of metal will affect operating range. This includes the metal in the car. 

•  The shape of the vehicle can affect range as well; vans in general have an especially poor 

range. 

•  The shape of the roof and A-pillars brings about considerable radio-frequency deflection (in 

this case the signal from the remote control). As a result, the direction in which the vehicle is 
facing in relation to the remote control can affect the range. Straight on – standing in front of 
the vehicle – generally gives you the greatest range; the second best performance is from the 
back. Using the remote control from either side of the vehicle will usually give the lowest 
range. 

•  The range will be significantly lower in a crowded parking lot than in open space. 

•  Always hold the transmitter high, approximately at shoulder height. Holding the transmitter 

against your chin will also increase your range: your head acts as an antenna.  

•  The operating range will be somewhat lower on vehicles equipped with an aftermarket or 

factory alarm.
