Saab Key Programming

saab 9-3 key fob Replacement cars built since 1994 feature an immobilizer system that is based on coded keys. A new transponder is required for addition of a second key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that this can be very costly. It is always advisable to keep a spare set of keys available.

Transponder key

The transponder is a key with an electronic chip. The chip sends a signal when the key is placed in the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are identical the car will be able to unlock itself and start. This is a great method to deter car theft and keep your car safe from thieves.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as safe as traditional metal keys. While the metal part of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computer in order to identify it.

When a saab key fob replacement key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. The car won't start in the event that the key is not programmed to match.

It is vital to have a spare Saab key. This is especially important especially if you reside in a rural location where there are many car thieves. The good part is that you can find a replacement key to your Saab without having to go to a dealership and pay the high costs that they charge. In most instances, you can get a new key made on-the-spot for less than half the cost you'd pay at an auto dealer.

Wired key

saab 93 key fob cars are usually supplied with two keys. If you only have one, it is an ideal idea to purchase an additional key fob as soon as is possible, because if you lose it, your car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be expensive particularly for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There is no standard method to do this, but it is crucial to plan how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together after which it is time to connect the key switches. To do this, put a diode over each key switch pin and solder it. This will protect the pins on the key switch from current and prevent them from being shorted. A diode can only allow the current to flow in a single direction, and it also has a an indicator of black color that shows the direction in which current will flow.

Sanabria says that some of the tools available in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunks to use in an emergency however, jumping a battery in newer vehicles might not be the best idea. They have numerous digital and electronic devices that communicate with each other. A voltage surge when the battery is connected another could cause damage to the components, rendering your car undriveable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the battery that is not working. 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 clean and unpainted metal surface under the hood of the damaged car. The engine block is a good option. Do not connect the black cable to the negative terminal of the dead battery as this could trigger an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you can begin the car and allow it to run for around five minutes. Then disconnect the cables in reverse. Be aware that the battery in the lost saab key 9-3 will be charged when you drive, and it could take a while for the battery to come back down again. You should invest in another key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab car key owners have only one key for their vehicle and if they lose that they'll be charged. It's expensive to buy keys and will require replacing the CIM or TWICE for older models. In the event of theft or any other calamity it is best to have an extra key. Even even if the key is "new" it will not work.

The dealer will charge you the most expensive dollars if you only have one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a new key without having to replace the entire system. That can save you a lot of money. It's also cheaper than waiting until you lose your one key.
