Saab Key Programming

Saab cars made since 1994 have an immobilizer feature that is based on codes for keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. You should always keep a spare set of keys on hand.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car then checks 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 stop auto theft and keep your car safe from thieves.

Transponder keys can be an extremely popular accessory for automobiles, but they are not as secure as traditional keys made of metal. While the metal component of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. The chip is equipped with an unique code that is encoded into the car's system to identify it.

The car will recognize the saab ignition key keyfob and allow 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 the original. The car will not start in the event that the key is not programmed to match.

It is essential to have a spare Saab key. This is particularly important especially if you reside in a rural area where there are many car thieves. You can purchase a new key for your Saab by visiting the dealership without paying their expensive prices. You can get a replacement key made on the spot at a fraction of what you would spend at a dealership.

Key for Wired

saab key programming near me cars typically come with two keys when they are new. If you only have one, it is an ideal idea to purchase an extra key fob as soon as is possible, because if you lose it, the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This could be expensive especially if you're buying a second-hand car.

The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. It's not a standard way to do it, but you must plan how 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.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode over each pin of the key switch and solder it. This will protect the key switch pins from current and keep them from being shorted. A diode allows current to only flow in only one direction. It has a visual indicator that is black, that shows which way current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY users in some cases program replacement saab car keys keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunks in case of emergency, but jumping a battery on modern vehicles may not be the best option. These vehicles are equipped with a number of computers and digital devices that communicate with one another. A voltage surge when the battery is connected to another one could cause damage to the parts making your car unusable.

Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface under the hood of the damaged vehicle. The engine block is a great alternative. Do not connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your saab milton keynes 9-3 is recharged as you drive. It may take a while it to drop back down. It's a good idea to invest in a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.

Replacement Case

Many Saab owners have only one key for their car and if they lose it, they'll be charged. It's expensive to buy the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other disaster it is best to have a spare key. Don't buy a secondhand key, even when it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail at the critical moment.

The dealer will charge the highest dollar for only one working key. We can, however, reset and re-program your computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This could help you save money. It's cheaper to do this rather than wait until you loose the only key.
