Comfort Access Got Me

[y5choi]

oh shoot, my bad, no I don't mean the engine. I see how this can be confusing.

What I do is, I put the gear in park, (foot off the pedal) press the button once (that shuts the engine but not radio, etc), get out and lock the door by touch (and that kills all the electronics) then walk away.

worked well for me since day 1.

Yah same here. I put the car in park, push the start/stop button once then get out and touch the handle to lock the car and have the electronics shut off.

As for driving without the key, you could run the car as normal when the key is taken out of the car but once you shut it off you can't start it again. Also, if you have CA and don't have the key with you, you can't lock the car with the handle, which sucks.

And I leave the car on and lock it a lot so it could be cool when I get back. I am thinking about getting the BMW "remote start" which is done by your cell phone I believe. I think you call a number and your car starts or something.

Understood. But if the car is running without the key, and you get out of range doesn't the engine shut off?

no, it runs normal but gives a message that the key is missing. It wouldn make sense for it to shut off.

Yeah, MBZ does the same. If the person who has the key/chip for Comfort Access/Keyless Go gets out of the car...on the MBZ, the speedo turns red, chimes and says "Key not detected". The engine and all features continue operating. You can turn the car off without the chip, but then you cannot restart of lock.

That's odd. I left the car running and went into a store but my mom stayed in the X. I park over the river and through the woods...far away from everyone. When I came back the X was off. I just assumed that the key was out of range so the engine cut off. I'd prefer it that way.

Hijack over.

I think your mom probably turned it off. I got scared the first time when my dad had the key in his pocket and walked into the store and told me to park the car. I thought it was going to shut off in the middle of the road, but no.

I think it is a safety feature. What if you are doing 75 on a highway and then CA system fails to contact the key (low battery, radio interference, etc). Do you want to have your engine shut in midflight?

Same logic works for loosing contact with the key while parked.

Either way, CA is not a replacement for a "bug"-based car security system. Hence, it does not have all bells and whistles, even though we would like to have these

My Infiniti behaves just like BMW CA, it chimes when looses the contact with the key but it remains fully functional otherwise.

I think the handshake with the keyfob is only done in the beginning (for starting). It then monitors that the unit is still inside the vehicle. If the keyfob crosses the boundary (set up by four antennas) it then shows the signal of loss of communication with key. They could easily make a time out counter to shut engine after a certain period and if you want to override your press start or somthing.

how preoccupied does one have to be to exit a running motor vehicle, lock the doors and walk away from same vehicle? dude put down the Blackberry. you are a hazard to yourself and those around you.
