I'd like to think it only works on older car, if it works at all !!!

 

works on old cars especially escorts lol,and its not the whole tennis ball u use,its one cut in half with a hole on the green side,place over the lock and bang the ball down,pressure pops the door poppers up and bang the doors open

 

Works on older cars? looks like your in the shit then Rich

 

thats why my escort rs turbos delocked and sos the boot haha

 

only works when the central locking works via vacum, old mercs are worst ones
