No other way.
Note: When you do get a replacement key - the old one wont start the engine any more. But the old one can still be used to get into the car. So, change the door locks on the front doors.

Requires reprogramming the key and the ecu.If someone has the equipment - you can try but I would not recommend it.

Not really sure about Toyota but in Skoda it's easy to flash a remote key and reprogram it with VCDS. Have done it myself a couple of times while upgrading components like CECM. Takes just 2 mins to flash any compatible key and reprogram it. It's a simple procedure.

Technically Toyota or any other car should have something similar but you need the cable and the respective OBD program to do this and any key of similar type.

Correct. Except that Toyota's OBD codes are not standard OBD 2. The generic scanners do not work very well on Toyota. Hence advised for main dealer support.

When I said "respective" OBD program, I meant Toyota specific and not generic. I think you got that wrong.

Most probably he might have to get it from the authorized centre itself which means he has no choice but shell out what ever it costs which I think would not be cheap. Chances of finding someone with a Toyota specific OBD tool may not be as easy as that of VAG cars. But, if at all that is a possibility, he could save some unnecessary expense. That's all I meant. Not trying to tell that this is a better option than going to the Toyota A.S.S. Just listed out a cheaper alternative for his info. as cost was a concern.

Bumping up an old thread here. Read a few threads on similar issues on lost keys etc.

It seems that the only completely safe option incase of a 'lost key' is to change the entire lock assembly.

Kind of renders the whole immobilizer concept pointless ?

I may be wrong but I distinctly remember my SA mentioning that the ECU needs to be remapped if the keys are changed. This is to register the new key-ecu and hence immobilizer combination.

This was for TATA cars, not sure of others.

Immobilizer concept is to prevent access to someone without the original key when they try to start the vehicle. It is not applicable in case of a lost key that is used to steal that vehicle.

The ECU would also need to be re-mapped to the frequency of the new set of keys once you change the lock assembly.

May be the experts can comment on the feasibility of this - if the frequency of the existing key can be updated along with the ECU, it might be sufficient to get a duplicate key generated based on the key number and the existing locks retained.

You are right, the ECU needs to be re-flashed with the new key data (frequency, codes etc) asking with the whole locking system requiring a change.

Why pointless?

The Immobilizer is there for good which protects the car from being stolen using some X Y Z key. If the codes/frequencies do NOT match, the Immobilizer kicks-in rendering the car useless.

Once a new set is made the brain (read ECU) needs to be informed and updated hence the re flashing and change of all locks need to be done.

It's just an adaptation procedure which flashes and matches the car and key with new codes. When you get a new key and adapt it to use with that particular car by coding, your old key would anyways be of no use. In VAG cars, you could erase the learnt keys and adapt a new set of keys to use with that car. Hence your old keys cannot be used to steal your car if those are erased and new keys are adapted to your car. Even your present car keys would not function after you erase the learnt keys. You have to carry out the adaptation for the keys to function again. There is a procedure for it which is simple. Even I could do it. Just takes a couple of minutes with VCDS on a VAG car. Other cars with similar tech., it should be the same.

However if you lost the whole set of old keys, lock might require a change as you might not be able to duplicate the old key pattern without a sample. If that could be done (which I doubt, or could it be done?), you wouldn't need to get the locks replaced. Security is not the concern here (for replacing locks), but actual matching of key pattern is. Like I said above, once all learnt keys are erased from the car, a key that matches lock pattern (even your car's old keys) would not start the car. Immobilizer is an electronic security aid. Lock is the physical one which is only the 1st step.

The key of my brother-in-laws Wagon-R was lost/misplaced by the driver today. Although he has a spare key with remote but will still not prefer to use it as the danger of theft will be looming large. The car is a 2010 model with the remote on the keys itself. The price quoted by Maruti owned and operated Service Centre at Naraina, Delhi is around 8-10k. According to them they will have to source it which will take a day or two and it will take a full day to replace all the locks and program the key. What I wanted to know is that is the price and time duration required justified and should we go ahead with the full replacement.

Thanks & regards !!

Get a duplicate key made from outside. Should cost around 2k for new key + remote.

The quote is correct, they will also arrange for reprogramming from nippon as well for the new keys as part of this. The keys will come from the factory and they may also ask you for a copy of the Service Manual where a key number is mentioned or the number on the tag of the old spare key.

In your specific case you can have the old lost key and the old spare deactivated, keeping only the new ones active.

In other cases e.g. old key broken, but not open to misuse, nippon can actually program the car in such a way that all 3 keys can be used together i.e. 1 old and 2 new will all work on the car.

This will also not apply when you change the locksets of your car.
