What is a Key Programmer

 

A car key programmer is a device that can be used to recode the transponder in a mechanical key or fob. Some modern automobiles have specially coded transponders in their keys and will not start or drive unless the correct signal is received. In some cases, a new key can be programmed without any special equipment, although many vehicles require a device called a key programmer. A key programmer can be a standalone entity, although sometimes integrated with complex scanning tools. Key programmers typically connect bi-directionally to the On-Board Diagnostic II (OBD-II) port.

When a key is replaced on a modern automobile, the new unit often turns the mechanical switch but fails to initialize the system or start the vehicle. When this occurs it is usually because the transponder in the key has not been coded for that particular system. Keys can often be obtained from either a dealer or a locksmith, although they must be coded regardless of source. Some vehicles allow the owner to code their own key, which usually requires the presence of one of their original keys. This process differs from vehicle to vehicle, although it usually consists of inserting the original key into the ignition, depressing a special combination of brake and accelerator pedals, and then replacing the original key with the new, uncoded one.

When a vehicle does not have a self-programming feature, a key programmer is usually required to do the job. These programmers are typically bi-directional OBD-II tools that connect to the same location as other scan tools. Many vehicle manufacturers sell units that program keys specifically for their vehicles, although generic units that can handle a variety of makes and models can also be found.

The process of using a key programmer typically involves plugging the tool into the OBD-II interface so it can communicate with the vehicle. Each programming tool has different options and procedures, although they usually allow the operator to retrieve the programming data from the computer and then recode the transponder and computer to make them work together. After using the key programmer, the new key should work the same as the old one.

Some vehicles use key fobs instead of traditional lock and tumbler keys. In some cases, the key fob only needs to be in close proximity to the vehicle to work, while other cars require it to be inserted into the dashboard. Key programmers can be used with these fobs in many cases and the process is usually similar to regular keys.

How to Remove a Locking Lug Nut Without the Key

In our previous article: How to Remove Wheel Locks Without a key Programmer Tool, we show a simple way to remove a lock nut without a key. In this instruction, we’ll show you some other different methods you can use to remove that pesky lock on Toyota.

Use a air gun or long ratchet to break free

Method two:

If you had a round lock, we could try to cutting out a little groove in the lug nut to help take it out. Be careful to protect the steel wheel.

Use a regular chisel like a caveman, grab onto that lip, apply a very little bit amount of pressure, especially you’re using your air chisel, and try to get it to turn and break free. And at all times, please wear hand protection and eye protection.

Method three:

Another way that you could try to get these out is by drilling out straight through the log nut and drilling out the stud on the other side. At that point, you’re either have to replace the stud with the lug nut or even the wheel bearing with the lug nut.

How to Program a Car Key

Programming a Key

Sit in the driver’s seat. You’ll need access to the car’s ignition switch in order to link the keys to the car’s systems. You may need two working keys to make or fix a third. Consult your owner’s manual for additional steps required by the manufacturer.
Search your car’s make and model online as well. You can find the exact steps needed to program keys for your car.

Turn the car on and off. Turn the key you placed in the ignition. Don’t start the motor. Simply turn the key to the on position, which activates the electrical system. Immediately turn the key back so the car shuts off.

Turn the car on and off with the second working key. You have about five seconds to remove the first key. Find the second programmed key and put it in the ignition. Again, turn the key so the car comes on without starting the engine. Turn the key back so the car shuts off.
