10 Things Everyone Hates About Saab Ignition Key Replacement
Saab Key Programming
Saab cars that were built prior to 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required to allow the inclusion of an additional key, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The issue is that this could be very costly. It is recommended to always have an extra 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 into the ignition. The car then examines the signal to determine whether it matches the one on the key. If the signals are in sync the car will then unlock and begin. This is a great way to protect your vehicle from theft.
Transponder keys are a popular feature in automobiles, but it is important to know that they are not as secure as classic metal keys. While the metal portion of a traditional key can be cut and copied the transponder is protected by an electronic chip. saab key programming contains an unique code which is programmed into a car's computers 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 will not 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 particularly important for those who live in a rural region where there are numerous car thieves. The good news is that it's possible to get a replacement key for your Saab without needing to visit an auto dealership and pay the high prices they ask. You can get a replacement key created on the spot at a fraction of what you would spend at dealerships.
Wired key
Saab cars usually come with two keys when new. If you only have one, it is recommended to purchase an extra key fob as quickly as you can as if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders need to be replaced. This can be costly especially if you're purchasing a used car.
The next step is to connect the column and row wires to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There is no standard method to accomplish this, however it is essential to determine the route you'll take and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered together It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode permits current to only flow in only one direction. It is equipped with a visible indicator of a black line that shows which way current will flow.
Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY users in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into OBD ports and help the customer through each step and make the process more straightforward than replacing the vehicle's computer.
Jump-starting the battery
Most people keep a set in their trunks to start a vehicle in the event of an emergency, but this might not be the best option for vehicles with newer technology. These vehicles are equipped with a number of digital and electronic devices that communicate with one another. A surge in voltage when the battery is connected to another battery could damage the components and render your vehicle unusable.
Start the vehicle that is working and allow it to run for around two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface under the hood of the affected car. The engine block is a great option. Don't connect the black cable to the negative terminal of the dead battery because this could cause an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, you can start the vehicle that is disabled and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will recharge while you drive. It may take a while it to recharge again. You should consider purchasing a second key fob, as soon as possible. Replacing the one that works requires the installation and programming of a new computer chip.
Replacement Case
Many Saab owners have only one key for their car and if they lose it, it's going to cost them. The reason for this is that it's costly to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's best to have a second key in case of theft or other disaster and the best option is to buy an extra key as soon as you are able to. Even when the key is "new", it won't work.
The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without the need to replace the entire system. That can save you a significant amount of money. It's less expensive than waiting until you lose your only key.
