My Toyota says key battery low

My Toyota says key battery low

I got a scary message from my 2011 Toyota Camry. “Key battery low,” the message on the dashboard read. You can read that two ways. “Key” could mean they key fob that unlocks and starts the car. Or “key” could mean “critical.” Fortunately, when a Toyota says key battery low, it means the key that unlocks and starts the car. Or the key fob, if that’s what your car uses.

You can fix this yourself and you don’t have to find a Toyota dealer.

Fare thee well, Radio Shack. Hello, Battery Shack!

The new owners of what’s left of Radio Shack want to specialize in batteries. Although this isn’t a guaranteed survival plan, it makes sense to me.

What you need to know to safely replace or substitute AC adapters

AC adapters inevitably break or get lost. That means you have to replace them to get your devices working again. But a lot of people don’t know how to do that safely. Here’s what you need to know when you need to substitute AC adapters.

If you lost the adapter and the specs aren’t on the device, try a web search on “ac adapter specifications” and the name of the product.

It used to be you could take the device to Radio Shack, and $25 and five minutes later you had a good replacement. Today you might try Batteries Plus for a similar experience. But if you’re willing to do the legwork yourself, often you can find a close-enough match for closer to $10.

So, with all that said, here are the handful of things you need to know when you’re shopping for an AC adapter. The specifications don’t have to match exactly, but you have to know when you can cheat and when you can’t. Read more
