5 Killer Quora Answers On Saab Ignition Key Replacement

Saab Key Programming

Saab cars built since about 1994 have an immobilizer feature based on coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that this could be very expensive. This is why it is important to always have a spare key on hand.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car then analyzes the signal to determine whether it matches the one in the key. If the signals match it will unlock and start. This is a great way to safeguard your car from theft.

Transponder keys could be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. The metal component of the traditional key can be easily cut or copied, while the transponder is protected by an electronic chip that guards it. The chip contains 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. The car will only recognize the key fob if it has an unmodified chip and programmed to match. The car will not start when the key isn't programmed to match.

It's crucial to ensure that you have a spare key for your saab ignition key (morphomics.science). This is especially important especially if you live in a rural area with numerous car thieves. The good part is that you can obtain a replacement key for your saab 9-3 key programming without having to go to an auto dealer and pay the high costs that they demand. In most instances, you can get a new key created on-the-spot at a fraction of the cost you would pay at an auto dealer.

Wired key

Saab cars usually come with two keys when new. If you have only one, it's a good idea to get an extra key fob as quickly as you can as if you lose it, your car will require a new CIM unit and the locking cylinders have to be replaced. This can be expensive especially for used vehicles.

The next step is connecting the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a great deal of soldering. There isn't a standard way to do this, but it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. To do this, put a diode on each pin on the key switch and then solder it. This will shield the pins from current, and prevent them from being shorted. A diode allows the flow of current to be in one direction, and it also has a an indicator of black color that indicates which way the current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can help shop customers or even DIY customers in some cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer in the vehicle.

Jump starting the battery

Most people keep an assortment of tools in their trunk to start a vehicle in an emergency, but it might not be a good idea for cars with more modern technology. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A surge in voltage when the battery is connected to another could cause damage to these components and render your car undriveable.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the non-working one. 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 beneath the hood of your disabled car. The engine block is an excellent alternative. The black cable should not be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, you should start the car and let it run about five minutes. Then disconnect them in reverse. Be aware that the battery of the Saab 9-3 will be charged during your drive, which means it may take some time to get the battery down. It is a good idea to purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose it, key, it will cost them. It's expensive to add a key and requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster it is recommended to have a spare key. Even if the key is "new" it won't work.

The dealer will charge you top dollar for only one working key. However, we can reset and reprogram the computer's EEPROM to accept an alternative key without replacing the entire system. This could save you a significant amount of money. It's cheaper to do this than wait until you loose the only key.
