Saab cars manufactured since 1994 feature an immobilizer system that relies on key codes. The addition of a key requires a new transponder, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends a signal when the key is put in the ignition. The car then checks the signal to determine whether it is the same as that of the key. If the signals are in sync, the car will open and start. This is a great way to deter car theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in vehicles, but it is important to know that they aren't as secure as traditional keys made of metal. The metal part of the traditional key is easily cut or copied, while transponders have an electronic chip that safeguards it. The chip has an unique code that is embedded into the car's computer 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 a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and won't start.

It is vital to have a spare Saab key. This is especially important especially if you live in a rural area with numerous car thieves. The good news is that you can find a new key for your Saab without having to go to a dealership and pay the expensive prices they ask. In most cases, you can have an original key made on the spot at a fraction of the cost you would pay at an auto dealer.

Wired key

Saab cars are typically delivered with two keys. If you own only one, it is recommended to get an additional key as fast as you can. This is because if the key is lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.

The next step is to connect the row and column wires to the microcontroller. This is the toughest aspect of the project and it will require a lot of soldering. There isn't a standard method to go about it, but you need to plan how to open a saab 93 without a key how to get a saab replacement key route and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and keep them from being shorted. A diode lets current only flow in only one direction. It features a visual indicator of a black line 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 the IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump starting the battery

Most people keep a set of jumper cables in their trunks in case of emergency, but jumping a battery on newer cars might not be the best option. These vehicles are equipped with digital and computers that communicate with each other. A voltage spike when a battery is hooked up to another one could damage these components and leave your vehicle unable to drive.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood--the engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery because this could trigger a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you need to start the vehicle and allow it to run for around five minutes. Then disconnect them in reverse. Be aware that the battery in the Saab 9-3 gets recharged when you drive, and it can take a while for the battery to go back down again. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your missing keys are not trying to steal the car.

Replacement case

saab replacement keys uk owners usually have only one car key, and if it is lost, they'll be charged. It's expensive to add a key and requires replacing the CIM or TWICE for older models. It's recommended to have a backup key in the event of theft or other disaster and the most effective way is to purchase a second key as early as you can. Even it's "new", it will not function.

The dealer will charge you top dollar if you only have one working key. We can, however, reset and reprogram the computer's EEPROM to accept the new key, without replacing the whole system. This could help you save money. It's cheaper to do this than waiting until you loose the only key.
