Saab Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system made up of coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

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

Transponder key

The transponder is a type of key that is equipped with an electronic chip. The chip sends a signal when the key is put into the ignition. The car will then check the signal to determine whether it is identical to the one in the key. If the signals match, the car will unlock and start. This is a great method to prevent auto theft and keep your car secure from thieves.

Transponder keys are a common feature in automobiles, however you must be aware that they aren't as secure as traditional keys made of metal. While the metal portion of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. This chip contains 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. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match the original. The car won't start in the event that the key is not programmed to match.

It's essential to ensure that you have an extra key for your Saab. This is especially important for those who live in a rural area that is home to many car thieves. You can get a new key for your Saab by going to the dealership and not paying their expensive cost. In most cases, you can have a new key made on-the-spot for less than half the price of what you'd pay at the dealer.

Wired key

Saab cars are typically delivered with two keys. If you only own one, you should purchase an additional key as soon as you can. This is because if the key is lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most laborious component of the project and it will require lots of soldering. There is no standardized way to accomplish this, however it is crucial to plan how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shorted. The diode will only allow current to flow in one direction, and has a a black band visual indicator that indicates the direction in which current will flow.

Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 are able to assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

Most people keep the set in their trunk to start a car in case of emergency, but this might not be a good idea for cars with more modern technology. These vehicles have many digital and electronic devices that communicate with each other. A voltage spike when a battery is hooked up to another could cause damage to these components, rendering your vehicle undriveable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the non-working one. 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 underneath the car's hood. The engine block would be an excellent choice. Do not connect the black cable to the negative terminal of the dead battery, since it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the vehicle that is disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in your saab 9 3 key replacement 9-3 will recharge while you drive. It will take a while for it to recharge again. You should purchase 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

saab car key replacement owners often only have one car key, and if that is lost, they will be charged. The reason is that it's costly to add a new key, replacement saab key and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other catastrophe it is recommended to have an extra key. Even if the key is "new" it won't work.

The majority of locksmiths won't be able to help when you only have one working key and the dealer will charge top dollar to replace the computer in your vehicle to make a replacement saab key. We can, however, reset and re-program your computer's EEPROM in order to prepare it to accept the new key without having to replace the entire system. This could save you a significant amount of money. It's also a lot cheaper than waiting until you lose your one key.
