What's Holding Back This Saab Ignition Key Replacement Industry?

Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer that relies on key codes. A new transponder is required in order to enable the addition of a second key, Saab Key Fob and SAAB key fob special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

This can be expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car then checks the signal to determine whether it is the same as the one in the key. If the signals are the same, the car will unlock itself and start. This is a great method to prevent car theft and keep your car secure from thieves.

Transponder keys could be an extremely popular accessory for cars, but they are not as safe as traditional metal keys. While the metal part of a traditional key can be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code that is inserted into a car's computers in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. The car will not start in the event that the key is not programmed to match.

It's crucial to ensure that you have a spare key for your Saab. This is particularly important especially if you live in a rural region that has many car thieves. You can get a brand new key for your saab replacement key by visiting the dealership and not paying their high costs. You can get a replacement saab 9-3 key key made on the spot for less than half what you would pay at a dealership.

Key for Wired

Saab cars typically come with two keys when new. If you only have one, it is recommended to get an additional key as soon as you can. This is because if it's lost and the car needs a new CIM and the locking cylinders replaced. This could be expensive especially if you're buying a used car.

The next step is to wire the wires for the column and row to the microcontroller. This is the most tedious part of the project and it will require a lot of soldering. There is no standard method to accomplish this, but it's important to plan out the way you'll route and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 columns.

After the rows and column are joined then it's time to connect the key switches. To do this you must place an inverter over each pin of the key switch and then solder it. This will protect the key switch pins from current and keep them from being shorted. A diode allows current to only flow in only one direction. It comes with a visual indicator, a black band, that indicates which direction current will flow.

Sanabria states that a number of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery on modern cars might not be the best idea. They have numerous digital and computer systems that communicate with one another. A voltage surge when a battery is connected to another battery could damage the components, rendering your car undriveable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface under the hood of your disabled car. The engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery, since this could cause an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle and let it run for about five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will recharge while you drive. It will take a while for it to fall back. It is a good idea to purchase a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that the lost keys aren't in the process of trying to steal the car.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose that it's going to cost them. It's expensive to buy keys and will require replacing the CIM or TWICE in the case of older models. It is best to have a spare key in the event of theft or other disaster, and the best way is to purchase a second key as early as you can. Don't buy a secondhand key, even it's "new." Claimed-new keys purchased from third-party sellers won't work and are likely to fail in the crucial moment.

The dealer will charge you the highest dollar if you only have one working key. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept the new key, without replacing the entire system. This can save you a great deal of money. It's also less expensive than waiting until you lose your only key.
