saab key programmer Key Programming

saab car key replacement cars that were built prior to 1994 feature an immobilizer mechanism that is based on codes for keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. It is always advisable to keep an extra set of keys on hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to the car when it is inserted into ignition. The car checks to see whether the signal matches with the one on the key. If the signals match it will unlock and begin. This is a great method to avoid auto theft and keep your vehicle safe from thieves.

Transponder keys are a common feature in automobiles, however it is important to know that they are not as secure as traditional keys made of metal. While the metal portion of a traditional key could be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code that is embedded into the car's computer to identify it.

When a saab replacement key key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do so if the key fob has an unmodified chip that has been programmed to match. In the absence of that, the car will reject the key and won't start.

It's important to make sure that you have an extra key for your Saab. This is particularly true if you reside in a rural area with numerous car thieves. You can obtain a replacement key for your saab 93 key fob replacement by going to the dealership without paying their pricey costs. You can have the replacement key on the spot at a fraction of the cost you would pay at a dealership.

Wired key

Saab cars are typically delivered with two keys. If you have only one, it is recommended to purchase an extra key fob as quickly as you can, because if you lose it, the car will require a new CIM unit, and the locking cylinders will have to be replaced. This can be costly particularly if you are buying a used car.

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 good amount of soldering. It's not a standard way 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 wires and pins to connect.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this, you need to place an inverter over each pin on the key switch and then solder it. This will shield the pins from current, thus preventing them from being shorted. A diode permits current to only flow in one direction. It comes with a visual indicator, a black band, that shows the direction in which the current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY users in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery on modern vehicles may not be the best idea. These cars are equipped with a variety of electronic devices and computers that communicate with one another. A voltage surge while the battery is connected to another can fry these components, rendering your car unable to drive.

Start the vehicle that is working and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is an ideal choice. Don't connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you need to begin the car and let it run for about five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will recharge while you drive. It will take some time for it to fall back. It is a good idea to purchase a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and special programming to convince it that your missing keys aren't attempting to steal the car.

Replacement Case

Many Saab owners have only one key for their car and if they lose it, the cost will be. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best 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 can. Don't buy a secondhand key even it's "new." Claimed-new keys from a second-hand store will not work and are almost guaranteed to fail at the critical moment.

The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM to accept an alternative key without replacing the entire system. This could save you lots of money. It's less expensive than waiting until you loose the only key.
