Saab Key Programming

saab replacement keys uk cars that were built prior to 1994 have an immobilizer system based on coded keys. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that it can be very costly. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car checks to see whether the signal matches the one on the key. If the signals are in sync the car will then open and start. This is an excellent way to protect your car from theft.

Transponder keys are an increasingly popular feature in automobiles, however you should be aware they aren't as secure as traditional metal keys. The metal component of the traditional key can easily be cut or copied, while transponders have an electronic chip that protects it. The chip has a unique code encoded into the car's system to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. However, it is only able to do so if the key fob has an unmodified chip that has been programmed to match. The car will not start in the event that the key is not programmed to match.

It is crucial to have an extra Saab key. This is particularly important when you live in a rural area, where there are numerous car thieves. The good thing is that you can find a replacement key to your Saab without having to go to an auto dealership and pay the high costs that they charge. In most cases, you can have a brand new key made right on the spot at a fraction of the price of what you would pay at a dealer.

Wired key

Saab cars usually come with two keys when they're new. If you own only one, it is recommended to get an additional key as soon as you can. This is because if it's lost saab key and the car is damaged, it 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 wires for columns and row to your microcontroller. This is the toughest part of the project and will require lots of soldering. There isn't a standard method to go about it, but you need to determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and keep them from being shorted. A diode allows current to only flow in one direction. It comes with a visual indicator that is black, that shows which way current will flow.

Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY users in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into OBD ports and help the customer through each step, making the process easier than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep the set in their trunks to jump-start their car in case of emergency, however it might not be a good idea for cars with more modern technology. They have numerous digital and electronic devices that communicate with each other. A surge in voltage when the battery is connected another battery could damage the components making your car unusable.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (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 choice. Do not connect the black cable to the negative terminal on the dead battery as this could cause an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you need to begin the car and let it run for about five minutes. Then, disconnect them in reverse. Remember that the battery on your saab key replacement (read) 9-3 is recharged during your drive, which means it could take a while for the battery to go down. It is recommended to purchase an additional key fob as soon as possible. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement case

Saab owners typically only have one car key, and if it is lost, they will be charged. The reason is that it's expensive to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other catastrophe it is best to have an extra key. But don't buy a used key, even it's "new." Keys that are claimed to be new from aftermarket sellers will not work and are almost guaranteed to fail in the most critical moment.

The dealer will charge you top dollars if you only have one working key. We can, however, Saab Key Replacement reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the entire system. This could save you a great deal of money. It's also a lot cheaper than waiting until you lose your sole key.
