Locking your car keys in the car today is a somewhat different situation than
it was 20 or 30 years ago. Car manufacturers have made cars harder to get into,
and new technologies like transponder keys have made them much more difficult to steal. It’s not a good idea to try to use a wire (like from a straightened coat hanger) or a Slim Jim to unlock your car, because lock mechanisms have changed in recent years, and if you’re not careful, you can detach the lock rods and render your locks unworkable even with a key.

If your car uses transponder keys, you rarely have to rely on the automobile
dealer to replace them or reprogram a new set, although some car makers will
tell you that you have to contact the dealer. Today’s licensed automotive
locksmiths have the proper software to program new transponder keys for almost
all makes and models of cars.

Say you have a set of Ford transponder keys. When you turn the key in the
ignition, a computer in your Ford sends a radio signal to the transponder
circuit. The circuit’s computer chip is programmed to send a special, coded
signal to the computer. If the code is wrong, or if the circuit doesn’t respond,
you can’t start the car. With transponder keys, forcing the ignition will not
start the car, making cars keyed this way more difficult to steal.

If you lose your transponder keys, when you call an automotive locksmith
Chicago, the locksmith uses a transponder blank, which hasn’t been programmed.
It can take half an hour or so for the key transponder to communicate properly
with the car’s system, resetting the electronics. You definitely want to have
the number on hand of an automotive locksmith experienced in programming
transponder keys if you need transponder car key replacement.

Ideally, you should have three properly programmed transponder keys so if you
lose one, you can use another. That’s not much help, however, if you cannot get
to your extras or find someone to get them for you. That’s why, before you ever
need a locksmith, you should do some research and find a trustworthy, licensed
locksmith and have their phone number programmed into your phone. You will feel
far more secure dealing with lost car keys if you do not have to worry about
finding a locksmith, or selecting one without enough information about their
qualifications and customer satisfaction.

You can call a locksmith to ask questions about response times and typical
charges for your type of car, and you can ask people whose opinions you trust
for recommendations. A good word-of-mouth recommendation means a lot in a world
where there are, unfortunately, a small minority of locksmiths intent on
cheating people. Like having a good mechanic or plumber, having the contact
information for a good automotive locksmith can give you much greater peace of
mind on your outings.

Choosing a reliable person to keep one of your duplicate transponder keys, or to
swap extra keys with is a good idea, too. It won’t guarantee you’ll never need a
locksmith, but it’s a good extra security measure.
