Leaving Your Dog in the Car With the Air Conditioning On? Don't Forget About the Mechanical Key.

If you're a dog owner, you've probably been there.
You need to run into a convenience store, pharmacy, or coffee shop for just a minute. It's a hot day, and you don't want to leave your pet in a warm vehicle. So you leave the engine running with the air conditioning on to keep them comfortable.
For many newer vehicles, however, there's something owners don't realize until it's too late.
Push-Button Start Changes the Rules
Many modern vehicles with push-button start (also called proximity or smart key systems) allow you to keep the engine running while taking the key fob with you.
The catch?
Once the engine is already running, the vehicle often disables the remote lock and unlock buttons. That's a safety feature designed to prevent someone else from driving away.
If you close the door behind you, the only way back into the vehicle may be with the mechanical emergency key hidden inside your smart key fob.
Does Your Vehicle Have a Mechanical Key?
Most proximity key fobs include a small metal key tucked inside.
Many owners have never used it.
Others don't even realize it's there until they're standing outside a locked vehicle with a very impatient dog looking back at them.
Consider Having a Spare Mechanical Key Made
If you frequently travel with your dog, a spare mechanical key can be inexpensive insurance.
Because it contains no electronics or battery, a simple metal key can often be carried in your wallet, purse, or on a separate key ring.
That way, if you intentionally leave your vehicle running with the air conditioning on for your pet, you'll still have a reliable way to unlock the driver's door.
