Saab Key Programming

saab keys cars produced since 1994 utilize an immobilizer system that relies on a set of keys. The addition of a key requires a new transponder and Saab Replacement Key Programming special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that this could be very expensive. Always keep a spare set of keys available.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car is able to check whether the signal matches the one on the key. If the signals match the car will then unlock and begin. This is a great method to protect your car from theft.

Transponder keys may be an extremely popular accessory for cars, but they are not as safe as traditional metal keys. The metal component of the traditional keys can be easily cut and copied, however transponders are protected by an electronic chip that protects it. The chip is a unique code that's 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 can only recognize the key fob if it is equipped with an unmodified chip and programmed to match. The car won't start when the key isn't programmed to match.

It is important to have an extra Saab key. This is especially important for those who live in a rural area where there are a lot of car thieves. You can get a brand new key for your saab replacement keys uk by visiting the dealership without paying their pricey cost. In the majority of cases, you can have an original key made on the spot for less than half the cost you'd pay at the dealer.

Wired key

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

The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. It's not a standard way to go about it, however, you should plan how to route and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and then solder it. This will shield the pins from current, preventing them from getting shorted. A diode allows current to only flow in one direction. It has a visual indicator of a black line that shows the direction in which the current will flow.

Sanabria states that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO or [Redirect-Java] IM508, can help shoppers or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep an item in their trunk to jump-start a car in case of emergency, but it might not be the best idea for newer cars. These vehicles are equipped with many computers and digital devices which communicate with each other. A voltage spike when the battery is connected to another could cause damage to these components, rendering your vehicle undriveable.

Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). 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. Do not connect the black cable to the negative terminal on the dead battery because this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, turn on the disabled vehicle and allow it to run for around five minutes before disconnecting them in reverse order. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to recharge again. You should consider purchasing an additional key fob as soon as you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners only have one key for their car and if they lose it, key, it will cost them. The reason is that it's expensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's recommended to have a backup key in case of theft or any other catastrophe and the most effective way is to purchase an extra key as soon as you can. Don't buy a secondhand key, even the case that it's "new." Claimed-new keys purchased from third-party sellers won't be effective and are almost guaranteed to fail at the critical moment.

The dealer will charge you top dollars if you only have one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This could save you a great deal of money. It's less expensive rather than wait until you lose the sole key.
