Saab Key Programming
Saab cars made from 1994 have an immobilizer that relies on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
The problem is that it can be very costly. Always keep an extra set of keys at hand.
Transponder key
The transponder can be described as a key that has an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then checks the signal to determine whether it is identical to the one on the key. If the signals match, the car will open and start. This is a great way to avoid car theft and keep your car secure from thieves.
Transponder keys are an increasingly popular feature in automobiles, but you should be aware they aren't as secure as traditional metal keys. The metal component of the traditional key can easily be cut and copied, whereas the transponder is protected by an electronic chip that guards it. This chip contains an unique code that's programmed into a car's computer order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do so if the key fob is equipped with a chip that is not modified that has been programmed to match it. The car won't start in the event that the key has not been programmed to match.
It's essential to ensure that you have a spare key for your Saab. This is particularly important especially if you live in a rural region that has many car thieves. The good news is that it's possible to obtain a replacement key for your Saab without needing to visit a dealership and pay the high costs that they charge. In the majority of instances, you can get a new key made on-the-spot at a fraction of the cost of what you would pay at an auto dealer.
Wired key
Saab cars usually come with two keys when new. If you own only one, you should purchase an additional key as quickly as you can. This is because if it's lost, the car will need an entirely new CIM and the locking cylinders 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 toughest part of the project, and will require a lot of soldering. There is no standard method to accomplish this, but it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and prevent them from being shorted. A diode lets current only flow in only one direction. It has a visual indicator, a black band, that shows which way current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and guide the user through each step, making the process easier than replacing the car's computer.
Jumpstarting the battery
The majority of people have an item in their trunk to jump start a vehicle in the event of an emergency, but it may not be the best idea for newer cars. These cars are equipped with a variety of digital and computer systems that communicate with each other. A surge in voltage when a battery is hooked up to another can fry the components and render your vehicle undriveable.
Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of the disabled car. The engine block is a great option. Don't connect the black cable to the negative terminal on the dead battery because it could spark an ignition spark that ignites the gasoline in the engine bay.
After the cables have been connected, you can start the car and let it run about five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to recharge again. saab 93 replacement key g28carkeys.co.uk is recommended to purchase a second key fob, when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Saab owners usually have only one car key, and if that is lost, they will be charged. The reason is that it's costly to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's best to have a second key in case of theft or any other catastrophe the best solution is to purchase an additional key as early as you can. Don't buy a secondhand key even it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't work and are likely to fail in the crucial moment.
The dealer will charge you top dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept the new key without having to replace the entire system. This can save you a significant amount of money. It's also a lot cheaper than waiting until you lose your one key.
