I want to start my car without a key. Can anyone recommend a good system to do this? I know that Mercruiser sells that Quicksilver keyless ignition kit for boats, but I would rather not use a keypad to turn on the accessories. Is there any type of proximity keyfob I could get that would work?

Ideally it would work like this...
1. I unlock the car with the remote
2. I sit down, flip the 'accessories' switch
3. Press a starter button to start the car

Now this is all fine, except there's no security aspect to it. So my question is, what's a good way to implement this?

thanks,

Matt

I think it would go more like this:
1. Thief breaks your window.
2. Thief flips "accessory switch".
3. Thief hits the valet button.
4. Thief drives away in your car.
Now the idea is cool and all but why would you do it? The gain is nowhere near worth the risk. As far as a keyfob type system goes, I don't really know of any aftermarket systems that work this way. But what will you do when your battery goes dead in your remote if you disconnect/remove the ign cylinder, which you will probably have to do in order to get around the steering wheel lock?

Okay,
Now if you read what I wrote...

"Now this is all fine, except there's no security aspect to it. So my question is, what's a good way to implement this?"

I.E., what is a good way to implement the security aspect of this?

As far as the keyfob, it will contain no battery, just like a proximity card. Remember, I'm not using this thing to remote start/unlock doors/etc, I'm using it simply so my vehicle identifies that I'm the driver.     

There are a lot of reasons WHY someone would want to this. I don't want to go through them all, but if you take a look at what Lexus and Mercedes-Benz are doing, you'll see they apparently found some utility in eliminating the use of keys.

I wasn't planning to make my car so just anyone can hop in and drive off with it, obviously. My question is, are there any good security "schemes" available to do what I want to do?

I give up.
Do yourself a favor, call a benz dealer and get a price on one of those keys. If you can afford two of those and afford to replace one when you drop it in a puddle, then go for it. The reason these car manufacturers can do this is because they have spent the money to make it secure. If you have the resources to design a system then do it, including your "proximity card". Now if you read what I wrote, I am unaware of an aftermarket system that does this.
Also as far as the security aspect of this, there isn't one. You will have to remove the steering lock in order for this to work correctly ( or there is no reason to bypass the key and if you are not trying to bypass using the key then there is no point this post), you will also have to wire the ignition to be able to start the vehicle with a button/system. Even installing a remote start on a vehicle makes it less secure, you basically give the thief everything they need in order to hot wire the car. Get where this is going? Just in case you don't, you just made it easy as hell for a thief to steal your vehicle.

if you want to implement good security into this, get an alarm. use the "ground when armed(-) output(commonly orange)" to activate 2 relays that cut the ground wires to each switch. when the alarm is on the switches will do nothing and neither will your starter button. send me an email and i'll show you how to do this without getting an alarm(by just using your door lock remote) But im not sure how you would go about getting around the steering wheel lock. questions@mycustomcar.com

The steering wheel lock is a snap, I would pray that all that works and noone vandalizes or puts your car on a flat bed, alarm or not.  Whatever you do, don't report it to your insurance company, changing a vehicles factory ignition is a serious no-no, they may deny any coverage. Before I was a locksmith, I had a junk, winter beater. The key got stuck in the on position, and I couldn't turn the car off, had I known what I know know, I would have just replaced it, but instead I threw in a starter button. It worked fine,but not a good idea, however, this is just my view.

This a very customized hot-rod type vehicle, which I have specialty automotive insurance on. No problems with modifying factory ignition because there is none :)
