Smart entry for the rear doors

I often have to open the back doors first. I've just gotten into the habit of touching the front door sensor and reaching for the back door in one smooth move. You don't actually have to open the front door.

BTW, for this to work you have to set your car up to unlock all doors when any of the sensors is activated. To do that hold down the LOCK and PANIC buttons on your remote at the same time and it will cycle through the 3 options. That setting is premanantly stored.

 

If I'm approaching the vehicle from the rear, I would just press the hatch release once to unlock all the doors (default setting) then open the rear door

 

What Toyota cars have rear door sensors? I'm only aware of the Prius and the Lexus as having Smart Entry options at all.

Realize this, too. Adding two additional continuously active oscillators will double the battery drain and, logically, shorten the already short half life of the battery even more...we'd start having a plethora of complaints about drained batteries after only a week of sitting locked.

I honestly can't believe this is an issue...the most convenient car entry and starting system on earth isn't convenient enough...it is simply second nature to slip my hand over to the front door sensor, unlock the car without opening the front door and then open the back. I do this same motion probably 3-5 times daily and sometimes more. If it was an inconvenience for anyone it would be me trying to wrangle a baby and two 5 year olds into the back seat, but it just isn't an issue at all and certainly not one worth complaining about....IMO.

 

Perhaps he means Toyota cars outside of NA. Maybe in Japan until next year when Lexus is launched. But yes, so far, all of these kind of smart key entry have sensors on all 4 doors (Infiniti FX, CLK-Class, E-Class etc, LS430).

Will the extra sensors really take a toll on the battery? Doesn't it run off the regular 12-V?

 

Yes, it really will. Yes it runs off the 12V battery, but it isn't a "regular" 12v, it's quite small and the SKS is the main drain on that 12v when it's active and will drain the 12v in about 2 wks with the current set up. The oscillation rate can be changed from the default of 300/min to 600/min to extend battery life, but each additional sensor is an additional drain. That is why the rear hatch sensor is not an active sensor. It has to be manually triggered by squeezing the button which turns on the sensor to see if there is a paired smart key in range.

If you added continuously active sensors to the rear doors and rear hatch you'd drain that battery in a few days. And everyone would complain about that.

Now, you COULD argue for manually activated sensors on the rear doors similar to the rear hatch. Or for a less directional or longer range on the oscilators with just a sensor to unlock when in range of the driver or passenger side oscillator I guess. But there's a little additional cost there. Somewhere along the line compromises have to be made to make a car that fits in the price bracket you wish to sell it in with as many features as you can while remaining profitable to build.

My point is that this is an extremely tiny sacrifice (lack of back door sensors) for what I got for my money. If you "want it all" you're going to need to be prepared to shell out about twice what you paid for the Prius and look at the Lexus 400H.

 

haha.. oops. Thanks for pointing that out. Yeah, CLKs are only coupes and convertibles with 2 doors I suppose the S-Class is more appropriate.

The new 2005 G35 sedan has the Intelligent Key System as an option. I'm not sure if that's for all 4 doors or not
