Replace Battery in key warning

Samsurfer · 11-17-2005, 08:43 PM

[font=Arial][size=7][color=blue]The warning to replace the battery in my key came up. I replaced the battery and the warning still comes up. Anyone else have this problem? Is the warning triggered by low voltage/signal in the key or is it just a time thing? If I press the bar that says "Don't show this warning again" does it reset or deactivate the timer or sensor?

I dunno about a reset, but..

Recommend a voltmeter to check the battery. I put the old one back in by mistake on another car! duh.

May have a bad battery, I noticed a filmy coating on one that suddenly worked after cleaning. Contacts too.

You mean it displays it on the MFD? Neat! I thought it was only a special beep.

Wait, are you sure that's what the message said, or is it the Car in Neutral warning? The "Car is in Neutral" warning will also come up if you open the driver door while the car is in Drive or Reverse.

The original intent of the warning I am thinking of was to let you know that if you leave the car in neutral, then the car can't recharge the HV battery, therefore you could run it down to a point where the car has to shut down. Toyota must have decided to use the same warning if you made a bonehead decision to try and walk out of the car while it was still in gear.

DanMan,

Yes, on the MFD. It said low battery. However I changed the battery and the warning still comes up. It only comes up when I turn off the car with the MFD in the Map mode. It has nothing to do with being in neutral. That is a different warning.

The low battery in key warning only stays up for 20 or 30 seconds then goes away until I start the car again.

Thanks for replying.

Is this feature only active on cars with NAV? Will it appear on the MFD of a car with package 6?

Thanks,

I have a 2005 prius and the electric key unlocks the car but does not lock it.

I have no warning light.

How do you get the key apart to replace the battery?

You read the owner's manual, where the process is outlined quite clearly.

I don't know why some people are so ungenerous.

Slide the latch at the end of the fob and remove the metal key. Slide the latch again and at the same time the back of the fob; it slides off showing a square plate held down by four screws. You need a #0 philips screwdriver to remove the screws and reveal the battery compartment.

I don't know why people don't read the owner's manual to their shiny $25,000 toy.

I don't know why people come here to be spoon-fed the instructions that are clearly outlined by the manufacturer. Lazy? Selfish?

I don't know why people spoon-feed said instructions to people too lazy to read the owner's manual.

One thing good about PC is that most members want to offer help to fellow members. I agree most things can be found in the owners manual but it can be and is confusing to a lot of us. I simple question here can make trying to figure out a problem a lot easier. Just reading the posts has given me more information than I ever got out of the manual. Many thanks to Bill and members like him.
