Bar-style steering wheel locks like "The Club" deter not only car theft, but for some cars they can also deter the increasingly common theft of air-bags.
FREE CLUB STEERING WHEEL LOCK
I just confirmed that P.G. Police District 6 is still offering free Club steering wheel locks for participation in the free Watch Your Car program. For information about Watch Your Car, see http://www.mdautotheft.org/wycprogram.htm but the web site does not offer the free Club steering-wheel lock.
To Register for Watch Your Car and get your free club lock, just drop by the P.G. Police District 6 statioin, 4321 Sellman Rd, Beltsville, MD (interactive map) and ask for Corporal Robison who usually is at the station Monday - Friday 8 am to 4 pm. Or you may call her at the station number 301 937-0910 to make an appointment.
Given what is at stake, even buying a club-style steering wheel lock may be a good investment.
