​Solutions for FERRARI 355 360 456 550 and 575 immobilisers

Questions &



Q. What is originally supplied with my Ferrari 355/360 456 550 or 575  ?

A: 3 remote "fobs", a red cased  "master" and 2 black "ordinary" remote fobs and the  pin code in a small paper envelope. as shown in the picture. If you have those items, you don't need our services.


Q. What is the pin code and why do I need it ?

A: The pin code is a numeric code supplied to the first buyer of a new 355,  360, 456, 550 and 575 Ferrari. The pin code allows you to start the car if a remote fob has stopped working - perhaps the battery in the fob has gone flat?. The code is also required to put the immobilizer in to  "learning mode " in order to replace lost or damaged fobs .The pin code is supplied on a small security envelope to the original purchaser of the car.  Most pin codes have been lost  during subsequent ownership changes. Having the pin code and all 3 remotes is becoming increasingly important if you ever want to sell  your car - buyers expect to receive "all the remotes and code" .

Q. What is the purpose of the red "Master" remote

A: The red "master" remote works the same as the  ordinarily remotes but it also contains the pin code and is required when programming the system to add "ordinary" remotes. 

Q. I have the pin code and original red "Master" remote but adding fobs doesn't work.

A: Once the pin in the red master fob has been transmitted to the immobiliser, the immobiliser will not recognise that pin again from the red master to initiate the programming sequence. The immobiliser will only recognise another (any other) pin sent from a red master to initiate the programming sequence. This is why Ferrari supply remote fobs as a set including a new master and pin, it's not possible to replace a missing fob unless you also have a new master and pin.  We can program a master with a new pin.

Q. I have one black fob and no pin code, what do I need ?

A: This is the most common situation owners face. Send us your immobiliser and fob, we will retrieve the pin code from your immobiliser and provide a pin code and 2 fobs: a red master and a standard fob and program the immobiliser to recognise all 3 remotes and the pin code.  

Q. Can you retrieve the pin code from a red remote?

A: Yes. If you have the red master there is no need to remove and send the immobiliser, simply send the red remote.

Q. I don't know where the immobiliser is located, can you help?

A: Yes, we have pictures and instructions that show you how to remove the immobiliser.


Q.:  How do you provide the correct pin code?

A:   I develop my own software to extract the PIN code and  I am 100% confident that I  can retrieve the pin code from your Ferrari's  immobiliser or red master remote and back it up with a guarantee that if  I can't retrieve the code, there is no charge for our services.

Q. Can you work out the pin code from the VIN?

A: No, there is no relationship between the VIN and the PIN on a Ferrari.

Q. How does your service work?

A: Contact us by email with your requirements, we will advise the cost and our shipping details. You'll will need to send your immobiliser or fobs to us in Canberra, Australia.  We suggest using tracked shipping via DHL / Fedx / UPS or similar. Upon receipt of the unit we will test it and retrieve the pin and request payment via Paypal. The immobiliser will be shipped back to you using DHL express or similar ( tracked & signed for).  

Q. Can you disable the immobiliser entirely?

A: This is a question that is sometimes asked. There is absolutely no good reason to do this. The Bosch system is reliable and provides a high degree of security and even provides a fall back method of starting the car using the pin code if your are unable to use your remotes. There are also significant liability issues that could arise from the theft of a vehicle where the OEM immobiliser has been disabled - for the owner of the vehicle and the supplier of such a device. Also In many countries it is a legal requirement to have a working immobiliser system. 

Q. What is the "Vehicle Immobiliser Interface" black box that's mounted next to the "Vehicle Immobiliser"?

A: The  Vehicle Immobiliser Interface is an integral part of the vehicle's immobiliser system and is matched with the immobiliser. We only require the immobiliser sent to us when retrieving the pin, but your immobiliser will only work with it's original, matching Vehicle Immobiliser Interface. (A mismatched interface will allow the car to be unlocked, but the engine won't start). An immobiliser without the matching Vehicle Immobiliser Interface is unusable.


Q. I have purchased an immobiliser, interface and matching fobs from a wreck and fitted it to my Ferrari 360 . When I press the remotes the doors unlock, but the car won't start.?

A: As an additional security feature, the immobiliser in the 360 and later Ferrari's is "mated" with one of the engine ECU's to prevent them being swapped from car to car, the vehicle simply won't start with an unrecognized immobiliser. You could swap the left and right engine ECU's in the hope that the other ECU is a "virgin" and has not been previously  "mated" to an immobiliser. If that doesn't work, you'll need to purchase some new, "unmated" engine ECU's from Ferrari. 

Fortunately the pin code retrieval service we provide avoids this problem entirely, because we can retrieve the pin from the specifc  immobiliser that was fitted  to your car


Q. I don't want to be without the use of my car while you retrieve the pin from the immobiliser.  Do you have advance exchange units in stock that you can send me?

A: This is not a good idea at all as the immobiliser is "mated" with one of the engine ECU's to prevent them being swapped from car to car - see previous answer. We do sell complete systems, but that's usually not the best way to proceed, our service was developed so you don't  have the expense of purchasing an entire new system. A new immobiliser is really a "last resort" solution if your unit it damaged and can't be repaired.


Q. The immobiliser in my car is faulty -  do you repair them?

A: Yes, often we can successfully repair your immobiliser. Typical problems are dry joints or damaged relays. We will quote you after we receive your immobiliser. 


Q. Do you provide a warranty?

A: We provide a warranty on our service, but not on the immobiliser you provide.  

If we are not able to retrieve a pin code, there is no charge for our service.

If  we have previously retrieved a pin code  for your immobiliser and you loose it, we will not charge you again for retrieving the pin code, provided you are still the owner of the vehicle.  This offer does not include freight & shipping costs.

Q. Do you keep records of PIN codes retrieved from immobilisers?

A: No, we do not keep such records for security purposes.

Q. Can I claim the cost  of lost remotes against my insurance?

A: That depends on your insurance policy, but many companies do provide coverage to replace lost remotes or keys.

Q. Do you provide keys as well ?

A: No.

Q. I have other question about my Ferrari immobiliser, can you help? 

A: Absolutely. use the contact form and we will be in touch

Q. You don't have a phone number or address on your website ?

A: Immofixer is a part time hobby enterprise that I do in my spare time and my work means that I'm not always available to take calls Send me your number and I'm happy to call you to discuss your immobiliser questions.
