A good steering lock cannot be taken "off in seconds".I turned off the keyless entry. I did not get a steering lock because the thieves take them off in seconds.
I'm trying to get a tracker insight of all these threads of cars stolen without a key.
A Disklok needs about 10 minutes with an angle grinder so imagine the noise and sparks with that.
Stoplock Pro is good too and might make them go elsewhere and find an easier car.
The visual deterrent may well mean your car is left alone.
