Yes. If you don't know what you are doing you might mess things up so that you won't be able to get the car to the shop. If you want to try, then this is the way to go about it. First thimg that you must do is to measure the resistance in that little chip in the upper part of the key, then you have to go to Radio Shack and buy a resistor with the same rating. The best thing to do is to solder the resistor in place but if you are not sure about that then make sure that you buy connectors, when you have all of the parts. You then remove the lower steering column cover you should then see two wires that are molded together with a plug about 18 inches from the cylinder where you insert the key (this is not actually the ignition switch). The wires that you are looking for are stiffer than the other wires under the dash if you have a problem finding the correct wires then you can go to the local public library and find the correct wiring diagrams (remember to take some change with you so you can make a copy of the correct page). I have 25 years experience in auto repair.

The pair of two wires under the column are often inside a thicker orange colored jacket that insulates them. Be sure to plan ahead so that the spot along the wires that you splice in the resistor will be in an area with the least amount of interference from other moving parts or your legs when getting in and out of car. If this delicate connection gets bumped or comes apart, your car wont start or wont stay running because the computer will shut down your injectors. A good rule to remember is to watch the yellow SECURITY light when you first turn on the ignition to start the car. It should go right back off. If it does not, you have to correct the problem and remember to wait 3 minutes between start attempts, even if you fixed the problem sooner.

All you have to do to save yourself some trouble is go to a car audio and security shop around your house and ask the main alarm installer there to draw you a diagram on how to bypass the key on your car. most likely he will be able to give you a copy of such diagram and he can also give you the part you will need to do the job. This will cost you no more the 30 bucks or so.
