Touch sense boot release

[jrhowie]

I have been looking into installing a remote keyless smart entry on my car and the only thing I can find fault with the whole thing is the boot.

The kit I'm looking at has a boot release button on the keyfob but that defeats the purpose of having it hands free so to speak. (more inconvenience than a major problem)

Would anyone on here know any way I could hook up a capacitance switch ( touch sensor ) to the boot release mechanism? And wire it in so it only works if the car is unlocked? And if not, would anyone be willing (once the system is installed) to perhaps design one? I'd be willing to pay for parts etc. Was thinking of mounting the switch next to the reverse cam somewhere so when you are in proximity, and the car is unlocked, all would be needed would be a light touch for the boot to open.

Something I'll be looking at hopefully in the not too distant future if anyone is keen to experiment.

Also, to save starting another thread, I need to get a bypass for the immobiliser in the car to install the smart system, and get confused with all the options on websites (xpresskit etc). Would an alarm installer know what to use in the Aurion?

What you're describing sounds similar in concept to the remote boot release that's on my VW CC. I wave my foot under the rear bumper (must have key FOB in pocket of course) and the boot pops fully open without me having to physically touch the car.

I don't know if this can be retrofitted to the Aurion though. Hopefully someone in this forum can help you out. Good luck, dude! ^_^

For real? Damn that sounds so neat.

On topic, anything can be made to work. What you want sounds simple enough. Just need to think of it when my head is more refreshed.

From what I can find in the manuals available. If it's the same set up as the camry, the boot release motor will open with a current straight from the battery. The tricky part is getting it to wok only when the car is unlocked. Once I install the smart key/ push button system I'm looking at, I should be able to use the 'ground-when-running' wire from that module to allow the boot switch circuit to activate.

Now having a look into the proximity switch under the bumper, on top of that, I'll have to find a way to make it run only when the car is not moving. So the boot wont pop when I go over a speed bump or reverse park too close to the curb. Also it seems that a proximity sensor for this application will be quite expensive. 400+ range.

There is a company in USA called intuitek that makes a capacitive touch switch which you stick behind plastic or glass which would be perfect however They don't supply overseas though so unless I find a yank who can middle man for me, it's not an option.

Ill be having a fiddle with the boot latch over the weekend and hopefully figure something out.

On a second thought I could try find a wrecker who has a vw cc and try and salvage the sensor from it.

jrhowie, late model Passat Highline models (Sedans not wagons, wagons have remote electric opening and closing tailgates instead) have this option too, just in case you have strike out trying to getting a sensor from a VW CC. There are more Passats on the road than CC's. It may sound like an interesting gimmick feature to have, but to my surprise I've found it pretty darn useful. Especially when you have both your arms full when you're heading to the car. It saves you fumbling for your keyfob remote boot release all the while juggling what you're carrying. All you simply have to do is just walk to the car, wave your foot under the rear bumper and the boot pops open. Voila!

I would LOVE to have this feature on my Aurion too, so I'd most definitely be interested in finding out if it's possible!

So after much avail, and long hours searching for a touch free proximity switch, the only ones i found which werent 2-3mm sensing distance, were $500+.

But the other day, performing a meanial task, I had a spark which has answered my questions.

As I waved my hand under the Hand dryers in the shopping centre bathrooms, I realised i had been searching too narrowly. So i expanded my search, found out what kind of sensors these use and managed to come up with some relatively inexpensive HF motion sensors, which have an adjustable distance of 3 - 80cm, and sends a digital signal when activated. So I figure with the correct setup with some relays it wouldnt be too hard to wire one of these up to open the boot using one of these sensors mounted on the underside of the rear bumper.

HOWEVER, the problem i forsee, is making this circuit only function when the car is UNLOCKED... so when i lock the car when i'm out, anyone who manages to activate the sensor wouldnt be able to pop the boot and take whatever is in there. This function would carry over once i install the smart key system on it, and would allow that when the keyfob is in range, the boot would be able to open without touching it.

On another thought, I would try and have to make it so the circuit would only function when the car is in park, so it doesnt open going over a speedbump. Or even parking too close to the curb in a reverse park.

Hopefully this project wont be too long in the making, but i need to find work first lol... I am hoping to be able to make this simple enough that i can make it up as a kit, and be able to share this with other people interested in making this useful mod.

Thought i'd update this, mostly to try and see if anyone can tell me how i'd be able to hook this up so it only works with it unlocked.

Will try and draft some wiring diagrams and post them up as this comes along.

You do realise that bypassing the immobiliser will void your insurance right??

It is possible to do but I don't recommend it.

It would be the same kind of bypass that would be installed if i had an aftermarket alarm system installed... The guys at toyota said i wouldnt have a problem with it warranty wise, i'll have to talk to my insurance company to see what they say.

No it's not. To have the remote start you have to bypass the factory immobiliser that is part of the transponder chip in the key head, if you bypass that there is nothing stopping someone from breaking into your car, forcing the ignition and driving off with your car.

If you are going to remove it you should check with the insurance company if they will be happy with you installing an after market immobiliser.

If you were only going to be adding an after market alarm you would still keep the factory immobiliser. The immobiliser is different to the factory alarm.

The system i am looking at installing prevents someone just 'jimmying' the ignition. The immobiliser will only be bypassed when the system detects the key within range. Without the key in range, the bypass remains as though it wasnt installed in the first place. So basically it tells the immobiliser there is a key there when there is actually a key. Otherwise, the car will act the same... No key = No start

But like you said, i will have to call the insurance guys and ask them.

having a think about how you can do your boot. I don't know what the electrical set-up is in the boot, but if you can find a circuit that only has power when the car is unlocked, you can connect a solenoid to the boot release rod and have the switch mounted on the boot near the lock, so when you push the switch it powers the solenoid opening the boot.

[jrhowie]

I've done a bit of research and from what i can tell, the boot release motor will activate with a direct 12v current running through it, so all i need to do is try and find out how to have that current run when the car is unlocked, and then put the switch in. I've decided to try and set it up with a motion detector under the rear bumper so i just have to wave my foot under the bumper and the boot will pop.

Is this what you were looking at http://www.xpresskit...x?productid=196

I don't know the product specificity but from what I can understand is that the module learns the information from the transponder in your key, this tricks the car so it always thinks that there is a key in the ignition. If this is how it works you might have issues when using the key that the module didn't learn from.

In the end you are still going to have to use your key to unlock the steering lock.

I believe that is the right bypass. (or one of the few that are reccommended) but the way it works is the smart key system has a "Ground when running" output which runs to the bypass so the bypass is only activated when the keyfob is in range of the car.

www.advancedkeys.com - I've done thorough research on this and wouldnt install it on my car if i felt it could be easily broken into and my car taken.

The steering lock is bypassed with a key cut (without the top end and left in the ignition. the ignition cylinder is then covered with a cover. Then a switch is installed on the 'acc' wiring so it doesnt drain the battery. (this is easier than having the steering lock disabled - easier to return to OEM if the need arises.
