I recently got a 'new' Toyota 2005 Corrola. It has a smart key (my first car with a smart key). I loose keys so I did this. (Yes, found on internet). Replacement keys for this car cost $100. So I had 3 dumb keys made and glued the smart key behind the ignition lock. Now the security system reads the nearby smart key signal and allows my dumb keys to work. I guess this is how 3rd party remote starters get around the problem of smart keys. I don't know if this will work with other cars. FYI ... you loose that security awarded by coded keys. (Cut the hidden smart key in half so that the key can't be used to start the car if found.) Does this generally work on all cars?

No, I doubt it will. Different cars use different systems. Some cars transmit a different signal every time the key is used. You destroyed a valuable key to disable a system. It's also going to signal the computer that the key is in the ignition all the time which on some cars will prevent it from locking. It may also increase your insurance rate if they find out security is disabled I definitely don't recommend doing this. It would be much smarter to just register a spare key and hide it somewhere. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

TOTALLY NOT MY GAME for starters! For the hassle, if you need a second key now go dupe the one you have and pay the $100 be glad it's only that and not lots more. **************** I don't think there's a standard to all vehicles by year or place for this crap (it is crap to me) did just what you did made dumb (keys) for spares was going to leave a real one hidden inside but not all vehicles will let you lock doors if one is nearby, or inserted. Gee thanks. To each their own this junk is a pest to some, myself included. I own my first vehicle (techs like me if any keep stuff forever or don't, I do. No valid reason for a tech to own new for their own if you are a tech keep on till it's destroyed by the elements or "knock on wood" some accident. OK: For the few I deal with (kinda retired but still do quite a bit mostly my own fleet) no keys just a thing nearby (is a key) and push a button on dash. Others (hear of this) can find just the frequency a chip key sends out and dupe that and you're good to use it no remote capability. I tried at a place that does that of course machine is down or no blanks of that try another but it's done - for some, not all. A Toyota I'd say yes too popular for places that did keys, locksmiths would think be stocked for those. I gave up too many real things to fix or do wanted OUT of keys that use a battery or chips that might fail and be stuck. *********************** A rant. I've got keys to home, shop, vehicles (5 vehicles for now) all in my pockets one has the remote buttons working on some other something heat it's hatch open I'm not at that vehicle. How special! Hammer Time you know here too may know or have an idea if you are dead set to do this - admitted up top this isn't for me rather a HUGE nuisance. Wish there was a common "valet" key many vehicles had those wouldn't open trunks, glove boxes or anything but start and move it to park it at places you can't the place doesn't have known parking. I'm in Metro Boston and yes there are many places they take your vehicle when a spot opens up put it in there hopefully tag it where they put it so far so good. Again, if you've got a price of $100 pay it IMO that's cheap vs tricks that may not work out well or fail easily? BTW I was told a real duplicate of my own "smart" key could be $400 so it hasn't happened yet - that "car" if you will is just a Jeep! Tom
