saab 9-3 key fob replacement Key Programming

Saab cars made since 1994 have an immobilizer system based on coded keys. To add an additional key, you need an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

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

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car checks to see whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and begin. This is an excellent way to protect your car from theft.

Transponder keys are an increasingly popular feature in automobiles, however you should be aware that they're not as secure as traditional keys made of metal. The metal portion of a traditional key can be easily cut and copied, whereas a transponder has an electronic chip that protects it. The chip has an individual code that is embedded into the car's computer to identify it.

The car will recognize the Saab keyfob and permit it to turn on. However, it will only do this if the key fob is unmodified and has a chip that has been programmed to match. Otherwise, the car would reject the key and not start.

It is crucial to have an extra Saab key. This is particularly important when you live in a rural area where there are a lot of car thieves. The good news is that it's possible to find a new key for your Saab without needing to visit an auto dealer and pay the expensive prices that they demand. In most instances, you can get a new key created on-the-spot at a fraction of the cost of what you'd pay at dealerships.

Wired key

saab ignition key cars usually come with two keys when they are new. If you own only one, you need to purchase an additional key as fast as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially if you're purchasing a used car.

The next step is to connect the wires of columns and row to your microcontroller. This is the most tedious part of the project and will require a lot of soldering. There isn't a standard way to accomplish this, however it is essential to determine the route you'll take and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode over each key switch pin and then solder it. This will shield the pins from current and prevent them from being cut off. A diode allows the flow of current to be in one direction, and has a an indicator in black that indicates the direction current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY users in some cases replace keys in the program and restore lost saab keys (have a peek here) immobilizer information, Sanabria says. The tools plug into OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump starting the battery

A majority of people keep an assortment of tools in their trunk to jump-start their vehicle in the event of an emergency, but it may not be a good option for vehicles with newer technology. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A surge in voltage while a battery is hooked up to another one could damage these components, rendering your vehicle unable to drive.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the one that is disabled. 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 a clean, unpainted metal surface underneath the disabled car's hood. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery because it could ignite an ignition that ignites the gasoline in the engine bay.

After the cables have been connected, you need to start the car and allow it to run for around five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will recharge while you drive. It will take some time for it to drop back down. It is recommended to purchase another key fob as soon as you can. Replacing the one that works requires the installation and programming of a new computer chip.

replacement key for saab 93 Case

Saab owners often only have one car key, and if that is lost, they will be charged. The reason is that it's not cheap to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other disaster it is recommended to have a spare key. Even even if the key is "new" it won't work.

The dealer will charge you the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This can help you save a significant amount of money. It's cheaper to do this instead of waiting until you loose the only key.
