saab car key replacement Key Programming

Saab cars manufactured since 1994 have an immobilizer feature made up of coded keys. The addition of a key requires a new transponder and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys on hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car is able to check if the signal matches the one on the key. If the signals are in sync the car will then open and start. This is a great way to protect your car from theft.

Transponder keys are a common feature in cars, but it is important to know that they aren't as secure as classic keys made of metal. The metal component of a traditional key can easily be cut or copied, while transponders have an electronic chip that safeguards it. This chip contains a unique code that is encoded into the car's system 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 when it has an unmodified chip and has been programmed to match. Otherwise, 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 for those who 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 key fob replacement without needing to visit an auto dealer and pay the high prices that they charge. In the majority of instances, you can get a new key made on-the-spot at a fraction of the price of what you'd pay at an auto dealer.

Key for Wired

Saab cars are usually delivered with two keys. If you have only one, it is recommended to purchase an additional key fob as quickly as you can in case you lose it, the car will require a new CIM unit, and the locking cylinders need to be replaced. This can be costly especially for used vehicles.

The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There isn't a standard method to do it, however, you should plan how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from getting shorted. A diode only allows current to flow in one direction, and it comes with a a black band visual indicator that indicates which way the current will flow.

A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY customers in some cases create replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep a set in their trunk to start a car in an emergency, but this might not be the best option for vehicles with newer technology. These vehicles are equipped with computers and digital devices which communicate with one another. A surge of voltage when batteries are connected to another one could cause damage to the parts, rendering your car undriveable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of the damaged car. The engine block is a great choice. Do not connect the black cable to the negative terminal on the dead battery because this could cause an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the vehicle that is disabled and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your saab 93 key fob 9-3 will recharge as you drive. It will take some time for it to drop back down. You should consider purchasing a second key fob, as soon as you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

replacement saab car keys Case

Many Saab owners have only one key for their car and if they lose it, key, it will cost them. The reason for this is that it's not cheap to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or any other catastrophe it is recommended to have an extra key. Even if the key is "new", it will not work.

Most locksmiths aren't able to help in the event that you only have one working key and the dealer will charge you high prices to replace the computer in your car to make a replacement. We can reset and reprogram the computer's EEEPROM for it to accept a new key without having to replace the entire system. This could save you a lot of money. It's also much less expensive than waiting until you lose your one key.
