Smart Key Questions

yes, you can have as many as you want and there is no master. they are expensive however. the 'push' button releases the metal mechanical key to unlock the door if the battery dies. and the case opens up to reveal a relaceable watch type battery. it's in the manual. all the best!

 

Our salesman said if you are out and the battery in the fob dies, use the physical key to get in and if you hold the fob next to your start button, it charges it...just enough so the car recognizes it so you can start it. After 6 months, I have no way to test this yet, nor have I really looked in the manual.

I'm doubtful on the fact that it charges it, but thats what he said (he was kind of an idiot tho), I'd assume in reality there is a tiny charge left and with the key close enough it can recognize it.

Either way, I hope its true just in case...

 

You can have up to four, actually. Unless they have changed the GIII from the GII.
Holding the FOB up to the start button doesn't actually charge it, it energizes the RFID chip inside and reads what it reply's with. Same as a "paypass" credit card. With a good battery in the FOB you can leave it in your pocket/purse.
The car won't want to lock with the FOB inside. It will emit three beeps outside to warn you.
When the FOB battery gets weak you will see a key appear on the dash warning you. It's easy to replace. I posted the battery type a while ago for both the GII and GIII (they are different).

After watching how people drive these days, I'd say it's MUCH smarter than most of us.

 

You can lock one fob in the car by using another fob to lock the doors... This blew our mind the other day when we accidently did this.

I find that 2 1/2 to 3 years you will need new batteries buy them anywhere and you can change them yourself and you can always toss a extra battery in the glove box

 

yes they pry open, not sure on programing a new one. Normally when you have the 2 org. fobs you can buy a 3rd FOB online [aka Ebay] and do it yourself.................... if you lose one the dealer must do it and you need the silver tag hanging on your spare remote

 

Appox $50 for a FOB and $90 with the A/C button on it

 

Prepare for some sticker shock on buying another fob from a dealer. About $250 for the fob, plus $100 to pair it with the car.

Best deal is to get a used fob off eBay and have a locksmith set it up. But first you've got to find a locksmith with the right equipment.

Another option is to purchase a new fob from an online dealer (about $150), and pair it by using the chicken dance. You'll still have to get the mechanical key cut ($35+).

 

This isn't supposed to happen. Either the fob left in the car has a bad battery, you hid it in some corner of the interior where it couldn't be sensed, or something is wrong with the key system. It would work this way with a 2004=2009 system without SKS (black logo keyfob), but your profile says a 2012...

 

Incorrect. It is possible to lock one fob in the car using the other one from a distance. But only if the car is off.

 

Agreed. The SKS system prevents locking a keyfob inside the car, but only if you use the button on the doorknob.

This is really good to know as there are times when you want to leave a keyfob inside the car. If you depend on the door handle button to lock the car, I thought the only way to lock it was to use a mechanical key. So all you need to do is use the lock button on the fob.

 

doesn't it unlock when you put your hand on the door?

 

Turned in the iV , bought an III 2010, miss the hatch door opener, Any one know if you can add this feature on to the car for the hatch open .

 

An interesting thing about the metal key is the bottom of it is designed to fit in the hole to pry the fob open.

 

To add a FOB they need to cut the key to your car. That uses a laser. Then they need to program the car to accept the FOB. Finally, I'm told they need to program the FOB to accept the car.

Last I heard, the car can accept up to four FOBs. Not sure if that has changed with the GIII.

 

There is a thread about how to do just that. Be advised to have someone do it for you would cost hundreds of dollars.
