But remember to check that it’s still there after you take the vehicle to a mechanic.
Ouch!
(The first time I attached The Club to my steering wheel…I turned it too far and broke my windshield from the inside. Drat!)
My car won’t start without the fob attached to the key. So the reason I would need a key is if I locked myself out. Which I have done. I bought a real estate combination lock box and epoxyed it to the bottom of my car and I keep only the key portion in the box, not a fob. Still there after all these years.
