Saab Key Programming

saab car key cars built since about 1994 feature an immobilizer mechanism made up of coded keys. Adding an extra key requires a new transponder, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. This is why it is important to always have a spare key on hand.

Transponder key

The transponder is a type of key with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car will check to see if the signal matches the one on the key. If the signals are in sync, the car will open and start. This is a great method to deter auto theft and keep your car safe from thieves.

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

The car will recognize the Saab keyfob and permit it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. In the absence of that, the car will refuse to accept the key and will not start.

It is vital to have a spare Saab key. This is particularly important if you live in a rural region where there are a lot of car thieves. You can get a new key for your Saab by visiting the dealership without paying high prices. You can get a replacement key created on the spot for less than half the price you'd spend at an auto dealer.

Key for Wired

lost saab car key key (pop over here) cars typically come with two keys when they are new. If you have only one, it's best to acquire an additional key fob as quickly as you can since if you lose it, your car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be costly especially for used vehicles.

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 good deal of soldering. It's not a common way to go about it, but you should think about how to program saab 9-3 key fob to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from being cut off. A diode allows the flow of current to be in one direction, and it also has a an indicator in black that indicates the direction current will flow.

Sanabria says that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 can assist shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jump starting the battery

A majority of people keep a set in their trunk to jump-start a car in an emergency, however it might not be the best idea for vehicles that are newer. These vehicles are equipped with numerous computers and digital devices which communicate with each other. A voltage spike when the battery is connected to another one could cause damage to the parts, rendering your car undriveable.

Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the disabled one. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block is a good option. Do not connect the black cable to the negative terminal on the dead battery, as this could trigger an ignition that ignites the gasoline in the engine bay.

After the cables have been connected, you need to start the car and let it run about five minutes. Then, disconnect them in reverse. Be aware that the battery of your saab replacement key 9-3 is charged while you drive, so it will take a while for the battery to go back down again. You should consider purchasing a second key fob, as soon as you can. Replacing the original 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 vehicle and if they lose it, they'll be charged. The reason for this is that it's expensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is recommended to have a backup key in case of theft or any other catastrophe the best solution is to purchase an extra key as soon as you are able to. Even when the key is "new" it will not function.

Most locksmiths can't help you with a single working key, and the dealer will charge high prices to replace the computer in your vehicle to create a replacement. However, we can reset and re-program the computer's EEPROM to accept a new key without replacing the whole system. This could help you save money. It's much cheaper than waiting until you lose the sole key.
