Yesterday my wife called from the grocery store. She'd unlocked the trunk, set her keys down, loaded the groceries and then....locked the keys in the trunk. Help.

I started the 20 mile drive and about 5 miles down the road remembered that I hadn't brought the keys to the Jag. I'd picked up my wallet and truck keys and headed out. Duh! Anyway, U turn and back to the house I go.

As I'm setting out on the second trip to rescue my fair damsel I had a bright idea. I called Joan and told her to hold her phone out to the car. I then pressed the unlock button for the trunk. No such luck.

It was worth a try but...why didn't it work? Do phones transmit such a narrow bandwidth that the signal simply didn't pass through or is it some other explanation. I have no idea where she held her phone when I tried this.

So....on I drove. At least I got to listen to Click and Clack.

 

Phones transmit a fraction of the audible frequencies. The remote uses others.

 

You should have called Click and Clack and asked them?

 

That's as I suspected. Thanks.

 

Are you with Optus or Vodafone?

 

Always carry a spare key.
