A Comprehensive Guide To Saab Ignition Key Replacement. Ultimate Guide To Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 use an immobilizer system that relies on keys that are coded. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
It can be costly. You should always keep an extra set of keys on hand.
Transponder key
The transponder is a piece of key that is equipped with an electronic chip. The chip transmits a signal when the key is inserted in the ignition. The car then analyzes the signal to determine whether it matches that of the key. If the signals are in sync, the car will open and start. This is a great method to stop auto theft and keep your vehicle safe from thieves.
Transponder keys are a common feature in vehicles, but you must be aware that they're not as secure as classic keys made of metal. The metal portion of a traditional keys can be easily cut and copied, whereas a transponder has an electronic chip that guards it. The chip has a unique code programmed into the car's computers to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. In the absence of that, the car will reject the key and refuse to start.
It is vital to have an extra Saab key. This is especially true when you live in a rural area, where there are many car thieves. The good news is that you can obtain a replacement key for your Saab without having to go to an auto dealership and pay the hefty prices that they ask. In the majority of cases, you can have a new key made on-the-spot for less than half the price of what you'd pay at a dealer.
Key for Wired
Saab cars typically come with two keys when new. If you only have one, it's best to acquire an extra key fob as soon as possible, because if you lose it, the car will require a new CIM unit and the locking cylinders will have to be replaced. This can be expensive especially for cars that are used.
The next step is to connect the wires for columns and rows to your 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 should consider how you will route and connect each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.
Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, you need to place a diode across each pin of the key switch and solder it. This will protect the pins from current, and prevent them from getting shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates the direction in which current will flow.
Sanabria states that a number of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508, can help customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. The tools connect to the OBD port and guide the user through the procedure, making it simpler than replacing the computer in the vehicle.
Jumpstarting the battery
A majority of people keep the set in their trunks to jump-start a vehicle in an emergency, however it might not be a good idea for newer cars. They have numerous digital and computer systems that communicate with one another. A surge in voltage when the battery is connected to another could cause damage to these components, rendering your car undriveable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface beneath the hood of your disabled vehicle. saab ignition key is a good choice. Do not connect the black cable to the negative terminal of the dead battery as it could ignite an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, you can start the vehicle you are not using and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to drop back down. You should purchase a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a brand 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 that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other calamity, it is best to have a spare key. Even it's "new" it will not function.
The dealer will charge you the most expensive dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement key without the need to replace the entire system. This can save you a significant amount of money. It's less expensive than wait until you lose your only key.
