Saab Key Programming
Saab cars made since 1994 use an immobilizer that relies on a set of keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.
This can be expensive. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder is a piece of key equipped with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car then analyzes the signal to see whether it matches the one in the key. If the signals match it will open itself and start. This is a great way to avoid car theft and keep your vehicle safe from thieves.
Transponder keys are a common feature in automobiles, but you must be aware that they're not as secure as traditional metal keys. The metal part of the traditional key is easily cut and copied, whereas the transponder is protected by an electronic chip which protects it. The chip is a unique code that is 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 can only do this if the key fob is unmodified and has a chip that has been programmed to match the original. The car will not start if the key is not programmed to match.
It is essential to have a spare saab 93 key programming key. This is especially important especially if you live in a rural region that has many car thieves. The good news is that you can find a new key for your saab keys replacement without having to go to a dealership and pay the hefty prices they ask. In the majority of cases, you can have a new key created on-the-spot for less than half the cost of what you'd pay at the dealer.
Key for Wired
Saab cars typically come with two keys upon purchase. If you have only one, it is recommended to get an additional key as quickly as you can. This is because, if it's lost saab key the car will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.
The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There's no standard way to go about it, but you should consider how you will route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are joined, it is time to connect the key switches. To do this, put a diode on each key switch pin and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. A diode allows current to flow in one direction, and it also has a the black band as a visual indicator that shows the direction in which current will flow.
Sanabria says that some of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools connect to OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.
Jump starting the battery
Most people keep a few sets of jumper cables in their trunks in case of emergency, but jumping a battery on newer vehicles might not be the best choice. These cars are equipped with a variety of electronic devices and computers that communicate with one another. A voltage surge while a battery is hooked up to another could cause damage to these components, rendering your car unable to drive.
Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface beneath the hood of the damaged vehicle. The engine block is a great option. Do not connect the black cable to the negative terminal of the dead battery, as this could cause an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, you need to start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. Be aware that the battery of your Saab 9-3 is recharged when you drive, so it could take a while for the battery to go back to normal. It's a good idea to buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that the lost keys are not trying to steal the car.
Replacement Case
Many Saab car Keys owners have only one key for their vehicle and if they lose it, the cost will be. 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, and programming. In the event of theft or other catastrophe it is advisable to have a spare key. Don't purchase a used key even if it's "new." Keys that are claimed as new from a second-hand store will not work and are almost guaranteed to fail at the critical moment.
The majority of locksmiths won't be able to help if you have only one working key, and the dealer will charge for the cost of replacing the computer in your vehicle to make a new replacement saab 9-3 key. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept the new key without having to replace the entire system. This can help you save money. It's cheaper to do this than waiting until you lose the sole key.
