Saab Key Programming

saab key fob repair cars produced from 1994 have an immobilizer system that relies on keys that are coded. A new transponder is required for the inclusion of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be very expensive. You should always keep a spare set of keys at hand.

Transponder key

The transponder is a key that is equipped with an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals match, the car will unlock and start. This is a great method to prevent car theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in automobiles, but you should be aware they're not as secure as traditional metal keys. While the metal component of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. The chip has a unique code that's programmed into a car's computers in order to identify it.

When a saab replacement keys key fob is used the car recognizes it and allows it to turn on. However, it can only do this if your key fob is equipped with a chip that is not modified that has been programmed to match. The car won't start if the key is not programmed to match.

It's crucial to ensure that you have an extra key for your Saab. This is particularly important for those who live in a rural area with many car thieves. The good news is that you can find a replacement key to your saab 9-3 key without needing to visit a dealership and pay the high costs they ask. In most instances, you can get a new key made on-the-spot for less than half the cost you'd pay at a dealer.

Wired key

saab 9-3 replacement key cars are usually delivered with two keys. If you only have one, you should get an additional key as quickly as you can. This is because, if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This can be expensive particularly for used cars.

The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There isn't a standard method to go about it, but you must think about how to route and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put a diode on each pin of the key switch and solder it. This will shield the pins from current and prevent them from being cut off. The diode will only allow the flow of current to be in one direction, and has a an indicator of black color that indicates which way the current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and help the customer through each step, making the process easier than replacing the car's computer.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunks in case of emergency however, jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with many computers and digital devices which communicate with one another. A voltage spike when a battery is hooked up to another can fry the components and render your car unable to drive.

Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of your disabled vehicle. The engine block is a great option. Don't 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, start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. Be aware that the battery of the Saab 9-3 will be charged while you drive, so it can take a while to get the battery back to normal. You should purchase another key fob as soon as possible. Replacing the only 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 car and if they lose it, they'll be charged. The reason for this is that it's not cheap to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or any other disaster it is recommended to have an extra key. But don't buy a used key, even if it's "new." Keys that are claimed-new from aftermarket sellers will not perform and are almost certain to fail at the critical moment.

Most locksmiths can't help you in the event that you only have one working key and the dealer will charge you top dollar to replace the computer in your vehicle to make a new replacement. We can, however, reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This can save you a lot of money. It's also a lot cheaper than waiting until you lose your only key.
