Hello Locksmiths :)
Can somebody check resistance of PCF7941 transponder reader in the key. Car is Smart Fortwo 2009.
Customer brought the car with broken antenna, tried many variants from 13 to 66 Ohm.
Thanks a lot

Interesting - i would of thought coil off another car would help prove ok as all same frequency. or u can wind antenna yourself with some wire.
