Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer system that is based on codes for keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

This can be expensive. It is recommended to always have a spare set of keys at hand.

Transponder key

The transponder can be described as a key with an electronic chip. This chip sends out a signal when the key is put into the ignition. The car then checks to see if the signal matches the one on the key. If the signals match, the car will open and start. This is a great method to stop auto theft and keep your car secure from thieves.

Transponder keys are a popular addition to cars, but they are not as secure as traditional keys made of metal. The metal component of a traditional key is easily cut and copied, however transponders have an electronic chip which protects it. The chip is a unique code which is programmed into a car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match it. The car will not start if the key is not programmed to match.

It is crucial to have a spare saab key replacement cost key. This is particularly important especially if you live in a rural area with many car thieves. You can get a brand new key for your saab 93 key fob replacement by visiting the dealership, without having to pay their expensive cost.

Key for Wired

saab key replacement cost cars are usually provided with two keys. If you have only one, it's an ideal idea to purchase an additional key fob as quickly as you can as if you lose it, your car will require a new CIM unit and the locking cylinders need to be replaced. This could be expensive especially if you're purchasing a used car.

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There is no standardized way to accomplish this, however it is important to think about the way you'll route and solder the columns and rows. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined, it is time to connect the key switches. To do this you must place a diode across each pin on the key switch and solder it. This will protect the pins of the key switch from current and prevent them from being shorted. A diode allows current to only flow in one direction. It has a visual indicator, a black band, that indicates which direction current will flow.

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain instances replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the vehicle's computer.

Jump-starting the battery

Most people keep the set in their trunk to start a car in case of emergency, but this might not be the best idea for cars with more modern technology. These cars have a variety of digital and electronic devices that communicate with each other. A surge in voltage when batteries are connected to another one could cause damage to the parts and render your vehicle unusable.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline inside the engine compartment.

After the cables have been connected, you need to begin the car Key replacement specialist and let it run for approximately five minutes. Then disconnect the cables in reverse. The battery in your saab 9-3 key fob programming 9-3 is recharged as you drive. It takes a while for it to drop back down. You should consider purchasing another key fob as soon as you can. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Saab owners usually have only one car key, and if it is lost, they will be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a second key in case of theft or other disaster, and the best way is to purchase an extra key as soon as you are able to. But don't buy a used key even the case that it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail in the most critical moment.

Most locksmiths can't help you if you have only one working key, and the dealer will charge high fees to replace the computer in your car to make a replacement. However, we can reset and re-program the computer's EEPROM to accept a new key without replacing the whole system. This can help you save a significant amount of money. It's less expensive instead of waiting until you lose the only key.
