Saab Key Programming

Saab cars made since 1994 come with an immobilizer system that is based on codes for keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The problem is that this could be very costly. You should always keep an extra set of keys on hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a great way to prevent car theft and keep your vehicle secure from thieves.

Transponder keys are a common feature in vehicles, but you should be aware that they're not as secure as classic keys made of metal. While the metal parts of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. This chip contains an unique code that is programmed into the car's computer to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. However, it can only do this if the key fob is equipped with a chip that is not modified that has been programmed to match it. If not, the car will reject the key and not start.

It's crucial to ensure that you have an extra key for your Saab Key Fob Repair. This is particularly true if you reside in a rural location that has many car thieves. The good part is that you can find a replacement key to your saab ignition key without needing to visit a dealership and pay the high prices that they charge. In the majority of cases, you can have a brand new key made right on the spot at a fraction of the cost of what you would pay at an auto dealer.

Key for Wired

Saab cars are typically delivered with two keys. If you own only one, you need to purchase an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. It's not a standard way to do it, but you need to determine how to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

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

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 are able to assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.

Jump starting the battery

A majority of people keep the set in their trunk to start a car in an emergency, however it might not be the best idea for vehicles that are newer. These vehicles are equipped with many digital and computer systems that communicate with each other. A surge in voltage while the battery is connected to another battery could fry these components and leave your car unable to drive.

Start the vehicle that is working and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of your disabled car. The engine block is a great 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.

Once the cables are connected, start the vehicle that has been disabled and let it run for about five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to drop back down. You should purchase another key fob when you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Many Saab owners have only one key for their vehicle and if they lose it, they'll be charged. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. In the event of theft or any other disaster it is best to have a spare key. However, don't purchase a secondhand key, even it's "new." Keys that are claimed as new from a second-hand store will not be effective and are almost guaranteed to fail at the critical moment.

The majority of locksmiths won't be able to help when you only have one working key, and the dealer will charge you high prices to replace the computer in your vehicle for a replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without replacing the entire system. This can save you a great deal of money. It's more affordable than wait until you lose the only key.
